Abstract

In this paper, an accurate method, using a novel immersed-boundary approach, is presented for numerically solving linear, scalar convection problems. As is standard in immersed-boundary methods, moving bodies are embedded in a ¿xed Cartesian grid. The essence of the present method is that speci¿c ¿uxes in the vicinity of a moving body are computed in an intelligent way such that they accurately accommodate the boundary conditions valid on the moving body. The ¿rst results obtained are very accurate, without requiring much computational overhead. It is anticipated that the method can be easily and successfully extended to real ¿uid-¿ow equations.
