中文摘要：

In this paper,the cell face velocities in the discretization of the continuity equation,the momentum equation,and the scalar equation of a non-staggered grid system are calculated and discussed.Both the momentum interpolation and the linear interpolation are adopted to evaluate the coefficients in the discretized momentum and scalar equations.Their performances are compared.When the linear interpolation is used to calculate the coefficients,the mass residual term in the coefficients must be dropped to maintain the accuracy and convergence rate of the solution.

Both the momentum interpolation and the linear interpolation are adopted to evaluate the coefficients in the discretized momentum and scalar equations. Their performances are compared. When the linear interpolation is used to calculate the coefficients, the mass residual term in the coefficients must be dropped to maintain the accuracy and convergence rate of the solution.
