ANALYTICAL STUDY OF NONCONTINUUM FLOW IMPINGEMENT ONTO A FLAT PLATE WITH AN ARBITRARY ANGLE
SINOPSIS
This work analyzes rarefied plume impingement on a flat plate with an arbitrary angle. For this problem, due to the rarefication effects we must use nontraditional analysis methods. A rarefied jet gas flows out of a two-dimensional nozzle and impinging on a flat plate was investigated with a gaskinetic method. With a relation between velocity directions and geometry positions, the corresponding sets of analytical solutions for the density, slip velocity, temperature, pressure, shear stress, and heat flux on locations very close or right on the flat plate were obtained. Numerical simulation results obtained with the direct simulation Monte Carlo method validate these analytical solutions. In general, the comparisons between the complex exact analytical solutions and the numerical results are virtually identical.
