Two-fluid analysis of a gas mixing problem
چکیده انگلیسی

The mixing pattern of two parallel gas streams initially separated by a splitter plate is analyzed in this study. A recently proposed, two-fluid model is utilized for simulation of the flow field. The model provides separate balance equations for each component species of the system. As a consequence of the strong resemblance of the two-fluid model to the Navier–Stokes equations, the same numerical methods are applied to these new equations. The computations are undertaken for two-fluid systems; one with particles of about equal masses and another with particles of quite distinct masses, and the corresponding results are compared. This clarifies how the mass disparity of the constituents may affect the establishment of the flow field. The influence of molecular interaction descriptions in the model predictions is also examined by comparing the results of a hard-sphere model, the Maxwell repulsive potential, and the Lennard-Jones 12-6 potential.
