HEAT TRANSFER FROM OXYGEN AT HIGH TEMPERATURES
Abstract
A theoretical and experimental investigation is reported of the heat transfer to the end wall of a shock tube behind a reflected shock wave in oxygen under conditions ranging from zero to nearly complete dissociation. Predictions of the temperature rise at the end wall as a function of the shock heated gas temperature are shown to be in good agreement with experimental measurements using thin film heat gauges over a temperature range of 500−4300°K. Results are also presented for air up to 2000°K. Failure to account for convection in the analysis is shown to lead to a significant overestimation of its thermal conductivity.
