			Abstract

In this paper we will investigate if implicit 
residual smoothing can be used together with upwind discretizations
when steady state solutions are computed.
We will numerically examine the second order accurate Roe's method
in different flow situations i two and three space dimensions.
These experiments indicate that 
a significant amount of CPU-time can be saved by residual smoothing
and especially the explicit version.
