Abstract:

Over the past several years the arc research studies have produced design for numerous unique arc facilities. They have also provided many advancements in the field of high temperature diagnostics and analyses. Spectrographic and calorimetric techniques have been developed to obtain temperature profiles and enthalpy levels of the air flow in the arc. Probe techniques have been developed to measure column voltage gradients and velocity profiles. Arc air radiation has also been examined both analytically and experimentally. A high pressure arc unit has beend developed which could be utilized to determine arc performance characteristics between ten and 100 atmospheres pressure. This unit could also be used for experimental verification of theoretical radiation heat transfer predictions for all conditions of planetary entry. In support of the experimental programs, the equations of motion and the energy equation have been integrated for velocity and temperature profiles. With the most recent analytical calculations of electrical and thermal conductivities and radiantt heat emission, the solutions of the energy euqation have yielded arc temperature profiles, voltages, currents, and flow rates which begin to correlate well with the same quantities measur d experimentally.
