Heat transfer from arrays of staggered diamond fins has been experimentally investigated by means of liquid crystal thermography and standard thermocouple / heating foil technique. The arrays present the diamonds either with high or low thermal conductivity. Local (per-module or spanwise averaged) heat transfer coefficients have been reconstructed and, when possible, separated to infer the individual contribution of diamond and endwall.

Abstract
Heat transfer from arrays of staggered diamond fins has been experimentally investigated by means of liquid crystal thermography and standard thermocouple / heating foil technique. The arrays present the diamonds either with high or low thermal conductivity. Local (per-module or spanwise averaged) heat transfer coefficients have been reconstructed and, when possible, separated to infer the individual contribution of diamond and endwall.
