AN EXPERIMENTAL DETERMINATION OF HEAT TRANSFER AND FLOW FRICTION CHARACTERISTICS OF PERFORATED MATERIAL FOR COMPACT HEAT EXCHANGER SURFACES

Abstract

The transient testing technique for the determination of heat transfer characteristics of a porous medium has been known since 1929. It requires a good deal of care and one of the important restrictions is that a step change in temperature must be applied to the medium at the beginning of a test run. The thesis involves the design, test and evaluation of an experimental set-up that utilizes an 'integral heater' to accomplish the step change in temperature. In addition, there is presented heat transfer and flow friction characteristics for a 20 degree skew matrix constructed from perforated nickel material. This data is compared to a 20 degree skew matrix made from stainless steel material. Also, data is presented for two 'parallel plate' matrices, one constructed from brass sheet, the other from perforated nickel material. A comparison of their relative performances is made.
