Usefulness of 3-D Time Dependent Models and Steady 2-D Models in Plasma Spraying Engineering?

This paper presents a 2-D, steady and 3-D, time-dependent models of the atmospheric–pressure plasma spray process. The former focusses on plasma jet and particle behavior while the latter involves the modeling of plasma jet formation inside the nozzle and makes it possible to have some insight in anode erosion and coating geometry. Both models have been validated by comparing the predictions against experimental data. The input and expected output of both models will be discussed as their use in the engineering and operation of plasma spraying
