ANALYSIS OF HEAT TRANSFER AND PRESSURE DROP FOR A GAS FLOWING THROUGH A SET OF MULTIPLE PARALLEL FLAT PLATES AT HIGH TEMPERATURES

Abstract

Equations are derived for heat transfer and pressure drop in a gas flowing through a heater composed of parallel, heat generating, flat plates operating at high temperatures. The effect of radiation between the plates is considered. The resulting equations were solved on an IBM 704 computer for a series of cases in which hydrogen was the working fluid with gas inlet and exit temperatures of 200 and 5000 R. The results presented are maximum plate temperature, flow distribution between the plates, and over-al pressure drop. The results also show the effects of laminar and turbulent flow, of changing the length to equivalent diaameter ratio of the heater passages, and of varying the emissivity and number of the plates.
