INTERACTION OF AN INCIDENT SHOCK-TUBE FLOW WITH AN ELECTROMAGNETIC FIELD: PART II-EXPERIMENT.
Abstract
An experimental study of the interaction of a high conductivity shock tube flow with a one-dimensional magnetohydrodynamic channel was performed. The aim of the study was to obtain sufficient diagnostic measurements of the gas dynamic, plasma and electrical properties of the interaction process to allow a detailed comparison to be made with a time dependent theory. This theory which is based on the Lax-Wendroff method includes the incident shock front and contact surface trajectories and it can predict the formation of secondary shocks in the interaction region. For simplicity the experiments were performed in xenon under thermodynamic equilibrium conditions and at Hall parameters less than one in the interaction region. Reasonably good agreement was obtained between theory and experiment. Exact agreement could not be obtained due to difficulties in theoretically reproducing the initial experimental plasma conditions. Both the theory and the experiments showed that a secondary shock wave is formed as the contact surface enters the interaction region. It was also shown that although the gas slug length was five times the magnetohydrodynamic channel length, the flow was non-steady in the interaction zone. (Author)
