Abstract
Recently, sandwich holography was proposed in heat transfer studies. This technique can provide the temperature gradient without the need to calculate the temperature map and then numerically differentiate it; also phase extraction and phase unwrapping are avoided. A numerical simulation was used to assess the performance of the technique. This investigation shows the ability of the method to obtain the convective coefficient h with an accuracy of about 6%. The measurement algorithm is also relatively robust with respect to noise.
