Abstract

This article deals with an application of the endoreversible thermodynamics theory of heat engine applied to micro-fluid flow power converters (MFPC). An analogy is demonstrated between thermal and fluid flow efficiencies. Maxi-mum power output and efficiency at maximum power are established for the device based upon the higher and lower pressure bounds. The linear and non linear fluid flows are considered with and without fluid friction losses. This paper provides theoretical limits for designing power flow converter. The best performances are obtained for linear fluid flow without flow losses.
