Abstract
This paper propose new equation of indicated power which allow the rapid and accurate calculation of pressure variation, flow friction losses in to the heat exchanger ( heater, regenerator, cooler ) and bend pipe in crank-driven Stirling engine, basis of Schmidt cycle that an isothermal thermodynamic model. These equation can be calculated flow losses given to the only main dimension of engine. These formulate are derived for frictional losses in the three heat exchangers and bend pipe, taking in to account the variation in mass flow rate, fluid resistance, gas flow, shaft torque over the cycle. In the previous report, the analysis on the flow loss work was carried out. Then, the technique which estimated the indicated power from principal particulars of the engine at the good accuracy was proposed. In addition, the analytic solution on flow loss work in bend pipe was deduced.
