Description
Summary:The appropriate choice of coordinate system so simplifies basic cycle analysis that computation of the ideal particle trajectory diagram reduces to a straightforward graphical process. Ideal pressure, Reynolds number Nre, friction factor Cf and heat-transfer parameters Nst and N2/3pr follow in function of location and crank angle via a few steps on the hand calculator. A thermodynamic design parameter is identified which has essentially the same numerical value for such diverse Stirling engines as Philips' MP1002CA, General Motors' GPU-3 and the turn-of-the-century Kyko hot-air engine.
