    Abstract

    Recuperater is used in micro gas turbine to recover the waste heat from the turbine exhaust and boost the thermal efficiency of the gas turbine. Effectiveness of the recuperater depends on the many factors; one among these is surface area for heat transfer per unit volume. This paper describes various fin geometries considered for improving the effectiveness of the recuperater used in Micro Gas Turbine. Through CFD analysis it was shown that inclined corrugated fins having 45 deg. inclination has higher effectiveness compared to conventional flat or straight corrugated fins. The flow within the corrugated channels was studied in detail to understand flow physics.
