<title>Fluid temperature measurement in an open cavity using a holographic interferometer</title>

Abstract

Heat transfer characteristics for natural convection in open cavity has been investigated by using the holographic interferometer. The diameter of test area exposed by interferometer was 130 mm. The study of open cavity was obtained with single flush-heated height 42.8 mm and width 58.8 mm. The vertical plate was uniformly heated and two horizontal surfaces were insulated. Experiment has been performed with changing of heat flux 5 W to 50 W from vertical plate. Experimental results are compared with the results of numerical code under same condition and the agreement is found to be good. Holographic interferometer was assumed to be an appropriate method of the study about heat transfer characteristics from the results.
