Abstract
Recuperater is used in micro gas turbine to recover the waste heat from the turbine13; exhaust and boost the thermal efficiency of the gas turbine. Effectiveness of the recuperater depends on13; the many factors; one among these is surface area for heat transfer per unit volume. This paper describes13; various fin geometries considered for improving the effectiveness of the recuperater used in Micro Gas13; Turbine. Through CFD analysis it was shown that inclined corrugated fins having 45 deg. inclination13; has higher effectiveness compared to conventional flat or straight corrugated fins. The flow within the13; corrugated channels was studied in detail to understand flow physics.
