Apparatus for Measuring High-Flux Heat Transfer in Radiatively Heated Compact Exchangers

Abstract

We describe an apparatus which can deliver uniform heat flux densities of up to 80 W/cm2 over an area 7.8 cm by 15.2 cm for use in measuring the heat transfer and pressure drop in thin (6 mm or less), compact heat exchangers. Helium gas at flow rates of 0 to 40 kg/h and pressures to 6.9 MPa (1000 psi) is the working fluid. We describe the instrumentation used in the apparatus and the methods for analyzing the data. We will use the apparatus initially to test the performance of prototype cooling jackets for the engine struts of the National Aerospace Plane (NASP).
