摘要
Two-fluid flows in domains with moving boundaries are encountered in specialized engineering applications. The present study focuses on the development of a computational method far the prediction of such flows using a combination of moving grids and the volume-of-fluid technique. Moving grids are used to accommodate the motion of the domain boundaries. The volume-of-fluid technique is generalized to moving grids for tracking the motion of free surfaces between two fluids in deforming domains. The method allows one of the two fluids to be compressible. Discretization is carried out using a control-volume method, and explicit time stepping is used for temporal differencing. The proposed method, presented for regular coordinates in two dimensions, can be readily generalized to complex domains shapes using curvilinear coordinates and to three-dimensional analyses. The computational method is applied for the prediction of gas-liquid flows in a reciprocating compressor. Results illustrate that the proposed method provides a convenient and powerful approach for predicting complex two-fluid flows in domains with moving boundaries. © 1996 Taylor and Francis.
