Abstract

The aim of the present study is to investigate the effects of density ratio between coolant and mainflow on a real engine cooling scheme of a combustor liner. Measurements of heat transfer coefficient and adiabatic effectiveness were performed by means of a steady-state Thermochromic Liquid Crystals...
