Abstract:

Studies of plasma jet interaction with cross flows has been made for development of the concept of enhancing of combustion and ignition at application of plasma jets. A computer simulation of a cross flow nitrogen plasma nitrogen jet from the divergent plasma generator in nitrogen has been carried out. This model involves a realistic equation of state, plasma radiation associated with plasma formation inside the plasma jet as well as coupling between the internal nozzle with external flow fields. Our model facilitates the application of the implicit free-Lagrange method for carrying out of computations, which have been carried out for jet injection angles 135 degrees into the cross flow. These show the complex and non-homogeneous structure of the flow. They represent the necessary step in understanding of applicability of the divergent plasma jets for propulsion enhancement.
