Abstract

This paper reports an initial study to test a new method for prescribing non-uniform wall temperatures on wind tunnel models. The ability of compact conformal resistive heater inserts to provide high, non-uniform wall temperature distributions was quantified, with potential application to wind tunnel models. This technique uses specially designed interchangeable reinforced-carbon-carbon resistance elements powered by a computer controlled power supply. Numerical simulations of the transient electrical heating of a range of candidate geometries have been performed using finite element methods. These simulations have demonstrated the efficacy of the heater design approach.
