Turbine Definition and 545 Threads

Hi there... if it is of interest to anyone. I just completed a wind turbine blade design and simulation software fully integrated into the GUI XFLR5 of Mark Drelas XFOIL. If you want to try it out check: qblade.de.to cheers David

I am trying to assess the feasibility of running a steam turbine from a heat storage device, which can produce in a heat range of 100°C to 600°C (with a respective increase in cost, to be compared with losses in efficiency of the turbine for lower temperatures). So my question is this: Where...

As an example what is the estimated distance between each blade of a Jet Turbine blade and how far would each rotary blade be from the other to compress the air within the turbine housing? My accomplishment would be to make a miniture sized electirc turbine, which i have made when i was 13...

anything big like it costs more then 15 million and some how it has made or is attempting to make a significant contribution to the field of physics. If it's happening in Canada then that would be most preferable and helpful but if it's taking place in a different country then that is good too...
