Book Description
One of the challenging problems in the plasma spray technique is reproducibility of the coating quality. This problem is mainly associated with arc behavior inside the torch, plasma-particles interaction and coating built-up that includes plasma-substrate interaction. To improve the understanding of the same, in this study, three-dimensional models are developed to simulate the plasma arc inside the torch and plasma-substrate interaction under various operating conditions. The effects of arc current and gas flow rate on characteristics of the arc and temperature and velocity distributions both inside and outside of the torch are explained. Using the nozzle exit profile predicted from the plasma arc model, the Ar-N2 plasma jet and conjugate heat transfer between the plasma and substrate are simulated by using plasma-substrate interaction model. The effects of arc current, gas flow rate, stand-off distance, substrate material and environment around the substrate on the temperature and velocity fields of the impinging plasma jet and thermal flux to the substrate are clarified. This model is validated by comparing the results of present model with previous predictions and measurements.

Book Description
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.
