    Abstract
  • In order to study the feasibility of the thrust vectoring using magnetohydrodynamic(MHD) control weakly ionized plasmas at low temperature, the experimental method based on the MHD control plasma flow theory was put forward. We established a MHD flow control experiment platform of seeds (alkali metal salts) induced gas ionization to research jet deflection vector angle under the condition of different temperature and different magnetic direction, and explored the feasibility of the numerical study MHD control by user defined function (UDF)loading the MHD model to solve the three-dimensional Navier-Stokes equations. It is demonstrated that injecting low ionization energy seed into the combustor can induce gas ionization, forming magnetic liquid and achieving thrust vector control under magnetic field; the numerical simulation results and experimental results of plasma flow deflection are consistent, meaning numerical simulation MHD flow control has a certain credibility.
