This paper presents a scheme on a moving grid for 2D flow where the effect of the grid motion is incorporated into a flux term. In constructing the scheme, metrics and Jacobian are estimated numerically so as to satisfy the GCL (Geometric Conservation Law). These are presented in detail. Adopting these metrics and Jacobian, two time-implicit schemes are presented respectively in order to efficiently calculate the flow fields on both an arbitrarily and a rigidly moving grid. The validity and accuracy of the scheme are examined by calculating some examples of the flow fields on a moving grid, where an example using Navier-Stokes equations Is included for practical use in the flow field analysis. Also the problems in GCL which appear in extending the method into 3D flow are discussed.
