Abstract
Methods of numerical simulation were applied to studying the interaction of high-temperature air jets arranged in a mixing chamber of a triple-jet plasma-chemical direct-flow reactor. Computations produce the 3D distributions for velocity and temperature in the mixing chamber. Simulation indicates the flow circulation zones and the spatial temperature distributions on the inner walls of the reactor. The study offers the data on the heat flux for inner walls depending on the existence/absence of a thermal protection coating on the inner walls. This approach can be used for numerical simulation for multiple-jet reactors with different designs and purpose.
