The investigation is carried out of the MHD influence on the flow about two models in the shape of a cone mated with a cylinder. At the cone vertex and along the mating line two electrodes are located between that an electric discharge is implemented, and inside the cylindrical parts magnetic inductors are housed. One of the models is equipped with a magnetic core inside the inductor. An appreciable difference between the influences on the gas flow about these two models was detected. Dependence of the MHD influence on the flow about the models depending on the polarity of connection of the electrodes to an external voltage source is found. Measurements of the heat flux toward the surfaces of the models are carried out. It is found that the induction of the magnetic field appreciably influences on the local heat load on the model surface. The object under study The object under study is the flow about models that are combinations of a cone with a cone angle of 60° and a cylinder 30 mm in diameter. Analysis of the results obtained and the capabilities of the experimental setup enabled us to design a model (in the shape of a cone mated with a cylinder) bearing all elements that are necessary for implementation of an MHD impact. The pulsed magnetic field is induced by a discharge of an external voltage source through the inductor located under the cylindrical model surface. The central electrode shapes the cone vertex, and on the conical model part near the line of mating the cone with cylinder the second ring electrode is located. The gas discharge between the electrodes in the presence of the magnetic field of the inductor starts to rotate around the model under the |
