Re: Bladeless MiniTurbine Doodles
Decimal point error correction for calculation of a MiniTurbine version of the IAS Bladeless Turbine. http://iaus.com/turbine.htm The calculations show that about 3.2 (STP) liters/sec water vapor exitingthe rotor orifices will produce about 20 electrical watts at about 1.0% of theoretical efficiency (based on 2260 joule/gram contained in the 0.72 grams of water vapor "propellent") compared to a Carnot efficiency of 1.5% for the 5 K temperature difference. Still not bad for a system that is scalable from milliwatts to megawatts. Frederick
Re: Bladeless MiniTurbine Doodles
Using the flow calculator: http://www.lenoxlaser.com/calculator/orifice.asp To see what 0.18 grams/sec water vapor at 330 K (135 F @ 130 torr) exiting from four 0.031 inch diameter tangential orifices on a 4 inch diameter hollow rotor in an air-cooled condensing chamber at 325 K ( 125 F @ 100 torr) spinning at 24,000 RPM ~ 400 ft/sec would do as a generator. The calculations show that about 3.2 (STP) liters/sec water vapor exiting the rotor orifices will produce about 20 electrical watts at about 12% efficiency compared to a Carnot efficiency of 15%. But, I wouldn't bet the farm on it. :-) Frederick
