Abstract
This paper proposes an experimental estimation of heat flow. Five-division model is employed to estimate the heat flow in each element from temperatures measured at the boundaries of the elements, and pressure. As measurement data, the result of multi-element simulation are used. Boundary mass flow, heat flow and gas temperature in the cylinders calculated with the 5-division model are compared with the results of the simulation. Boundary mass flow and heat flow in the heater and cooler were almost the same as those of the simulation. However the results of the heat flow in the cylinders show some discrepancy. But this method may be used in the ordinary situation where heat transfer in the cylinders can be assumed negligible. Heat transfer coefficient estimated experimentally would be used for more realistic design of Stirling engines.
