SAMCEF for Wind Turbines
SAMCEF for Wind Turbines (S4WT) is a unique software product for the global design and detailed verification of Wind Turbines. It offers a complete solution providing, for the first time, the possibility to use experimentally validated models, computation procedures and specific post-processing in a user-friendly environment
For centuries, people have used the power of wind for sailing ships, milling grain and pumping water. More recently, wind turbine technology has enabled us to harness wind to generate electricity. Today, wind power is the world’s fastest growing energy source. The wind industry continues to expand and must develop larger, more reliable and more efficient wind turbines.
Building a highly reliable wind turbine is a big challenge. Wind turbines are large flexible structures submitted to aerodynamic transient excitations. These dynamic loads may result in significant mechanical problems, sometimes with dramatic consequences such as failure of gear pinions, bearings… resulting from dynamic loading and fatigue…
SAMCEF for Wind Turbines (S4WT) is the answer to your problems involving both design and verification of complete wind turbines.
Your Benefits with SAMCEF for Wind Turbines
S4WT takes advantage of the 20 years’ experience SAMTECH software and results from an interactive partnership with industrial actors (validation of S4WT with experiments). With S4WT, you enter in a cutting edge technology:
You work in a user-friendly environment using pre-defined validated models that can represent backlashes in the gears, clearance issues in the bearings…;
You simply introduce your parameters (for each component of the wind turbine) in the existing models;
You can replace some components by your own and re-introduce them in a complete model to check your wind turbine design in a global framework;
You choose a pre-defined analysis to launch (dynamic load amplification, start-up, e-stop, fatigue…) or set one up yourself;
You have access to specific postprocessing tools (Load Duration Distribution & Rain Flow Count results, Waterfalls and Campbell diagrams…): results are available for every component;
You use a high quality product able to increase your wind turbine reliability;
You will work with increased efficiency, saving both time and money. |

Thank you for your continued patience with my site. I appreciate your coming by. It seems my sort of blogging of tid bits of numeric facts with some commentary just is not hitting it big time. Your site is a gold mine of activity. Keep it up.As for your question in the summertime when it is hot from Montana to Ohio and down to Texas, it is usually one big high pressure region with no storms and no cold fronts, so the air just sticks, and the wind speed is less than 10mph not fast enough to spin the turbine. That is why wind does so lousy on hot summer days with stagnant air and sunny hot weather. In the Fall and Spring when things get juiced up with cold fronts and lots of storms all over the place the wind is blowing a plenty and then the wind mills turn good time. In the winter when we are all tucked inside, it is actually more windy than in the summer, so the wind mills work better then too. During the summer, unless a major cold front is impinging on hot humid weather, the summer days are lazy and the wind mills follow suit.

Well the Spanish added nearly the same amount in 10 years and it's been a big success so it's likely do-able. Offshore might be more expensive but then there is also a lot more return. It is possible to combine with hydro or combined heat and power plants to even the load but yes older carbon and nuclear plants will still be needed. How many new plants are needed is down to whether efficiency overall can be reduced: negawatts via better insulation and geothermal heating can do a lot of that. Coal to gas tech is also being tried on the firth of Forth and could be tried on other currently abandoned deep coal mines where there is around 200 years worth of coal.The real problem is that the UK doesn't have the money for any public projects and they didn't do anything even when they did have the money. With the ever-increasingly huge sums needing to be spent on decommissioning old nuclear plants, unless a miracle happens they have the choice of the private sector or going bankrupt.

Let me start off by saying that I am no exerpt in this field, but I am responding to tell you about what I found out when looked into it for my home.There is a special converter that needs to be hooked up to your homes electric that will keep the systems separate but yet compatible. And yes, ones that will give you enough power for a modern home are quite expensive, it was almost thirty thousand for three wind generators without installation and that would have not met all my needs. The amount of time for the payback made me scrap the idea. Some of then will require battery banks to be installed and these will need maintenance and eventually replacing. Another issue is the noise and vibrations they cause, some are better than others and most are recommended to be installed on a pole, seen one company that claims they have overcome these issues and theirs can be mounted on the roof of your home.Again, I am not an exerpt and they may work for you, talk to a few companies about them and you will be able to better decide. There are probably a lot more options out there than I looked at.

Ok, in my opinion, wind turbines and solar panels are a fad that is not economically viable. It simply costs too much money, manpower, land, and other resources to take those diffuse sources of energy and concentrate them enough to make them usable for ordinary people on a 24/7 basis. However, your question had more to do with what major to pursue and the answer to that is whether or not you want to pursue a “hard” science or a “soft” science. Mechanical engineering is a “hard” science because there are definite answers to the problems you will face. Mechanical parts either work or they don’t work and you should be able to predict that before you make them. Environmental engineering is a “soft” science because when you start messing with ecosystems you really can’t accurately predict what the impact will be. There are huge “unintended consequences” that you just don’t find as often in hard sciences.So, are you a person who needs concrete answers, or are you a person who prefers soft fuzzy answers. Also, as an engineer, you will have to deal with a lot of paperwork. A mechanical engineer doesn’t deal with as much paperwork as an environmental engineer. So, do you want to spend most of your time at your desk, or in the field getting your hands dirty? Environmental engineers are usually stuck in huge bureaucracies like government or large companies. Mechanical engineers are found in organizations as small as a partnership and as large as GE.As a nuclear engineer, I am stuck in an office for 95% of my time dealing with paperwork. It pays really well, but is dull and not fulfilling. Nuclear engineering in the U.S. has been on the cusp of a renaissance for about 15 years now and hasn’t moved off of top dead center. The Japanese earthquake and resulting issues at the Fukushima Daiichi facility hasn’t helped. However, in the rest of the world there are nuclear programs going full speed. So, you might need to get out of the U.S. if you go in the nuclear direction.

It pays really well, but is dull and not fulfilling. Nuclear engineering in the U.S. has been on the cusp of a renaissance for about 15 years now and hasn’t moved off of top dead center. The Japanese earthquake and resulting issues at the Fukushima Daiichi facility hasn’t helped. However, in the rest of the world there are nuclear programs going full speed. So, you might need to get out of the U.S. if you go in the nuclear direction.

Ok, in my opinion, wind turbines and solar panels are a fad that is not economically viable. It simply costs too much money, manpower, land, and other resources to take those diffuse sources of energy and concentrate them enough to make them usable for ordinary people on a 24/7 basis. However, your question had more to do with what major to pursue and the answer to that is whether or not you want to pursue a “hard” science or a “soft” science. Mechanical engineering is a “hard” science because there are definite answers to the problems you will face. Mechanical parts either work or they don’t work and you should be able to predict that before you make them. Environmental engineering is a “soft” science because when you start messing with ecosystems you really can’t accurately predict what the impact will be. There are huge “unintended consequences” that you just don’t find as often in hard sciences.So, are you a person who needs concrete answers, or are you a person who prefers soft fuzzy answers. Also, as an engineer, you will have to deal with a lot of paperwork. A mechanical engineer doesn’t deal with as much paperwork as an environmental engineer.

Thank you for your continued patience with my site. I appreciate your coming by. It seems my sort of blogging of tid bits of numeric facts with some commentary just is not hitting it big time. Your site is a gold mine of activity. Keep it up.As for your question in the summertime when it is hot from Montana to Ohio and down to Texas, it is usually one big high pressure region with no storms and no cold fronts, so the air just sticks, and the wind speed is less than 10mph not fast enough to spin the turbine. That is why wind does so lousy on hot summer days with stagnant air and sunny hot weather. In the Fall and Spring when things get juiced up with cold fronts and lots of storms all over the place the wind is blowing a plenty and then the wind mills turn good time. In the winter when we are all tucked inside, it is actually more windy than in the summer, so the wind mills work better then too. During the summer, unless a major cold front is impinging on hot humid weather, the summer days are lazy and the wind mills follow suit.
