Abstract

A calculation procedure is proposed for heat and fluid flows in geometries with a time-dependent boundary. The procedure incorporates a moving mesh arrangement with multi-block iteration and has been developed to assist future simulations of heat and mass transfer with phase change. The solver for the basic equations is the SIMPLE algorithm with a non-staggered grid arrangement. The space conservation law is invoked and applied for the explicit tracking of a moving boundary with a moving mesh. For mapping complex geometries a multi-block iteration strategy is employed. A cubic spline interpolation allows the "uniqueness of zonal boundary" requirement to be met. An interpolation method is also developed for variables near the zone boundaries. The calculation procedure using multi-block iteration and a moving mesh is applied to three benchmark-testing problems. The numerical results are in very good general agreement with available experimental data.

More information

Published date: 2002
Additional Information: This paper proposed a numerical method for calculating heat and flows in time-dependent geometries, combining strategies of a multi-block iteration and a moving mesh. This is a first step of establishing a basic algorithm so as to numerically study the micro heat and fluid flows in deformable rising bubbles.
