Abstract

In fluid mechanics, it is well accepted that Euler equation is a truncated form of the Navier-Stokes equation by neglecting the viscous effect. There are a few truncation techniques currently being used in order to truncate the Navier- Stokes equation to a reduced form. This paper describes a modification of the technique suitable for adaptive domain decomposition methods in order to solve boundary layer problems. The physical domain of the boundary layer problem is split into viscous and inviscid subdomains without overlapped regions, and the technique is embedded in a control-volume finite element method. Some numerical results are provided for a flat plate problem. Implementation issues parallel processing systems are discussed. on 1 Introduction The nu
