Abstract:

A computational model has been developed and applied for calculating radiant heat flux from an electric arc using real gas properties and taking into account both self absorption and space varying temperature. The model requires knowledge of the temperature profile as an input. Temperature profiles were measured spectrographically using an air arc at one and 2.4 atmospheres. These measured profiles plus some simple analytic ones which satisfied boundary conditions were used to calculate radiant heat flux at pressures from 1 to 300 atmospheres. The experimental program also included measurements of radiant flux density at 2.2 and 5.7 atmospheres for comparison with calculations based on the measured profiles. Estimates were made of radiation losses in the AEDC 20- megawatt arc air heater now under development.
