Technique to Calculate Cell Face Velocity of a Non-Staggered Grid System
摘要
Abstract
The calculation of cell face velocity in the discretization of continuity equation, momentum equation and scalar equation of a non-staggered grid system were discussed. Both momentum interpolation and linear interpolation were adopted to evaluate the coefficients in the discretized momentum and scalar equation, and their performances were compared. When linear interpolation was used to calculate coefficients, the mass residual term in the coefficients must be dropped to maintain the solution accuracy and its convergence rate.关键词
