Unlike Eulerian methods it is not convenient to reduce the effects of viscosity by means of switches based on spatial gradients. In this paper we introduce the idea of time-varying coefficients which fits more naturally with a particle formulation. Each particle has a viscosity parameter which evolves according to a simple source and decay equation. The source causes the parameter to grow when the particle enters a shock and the decay term causes it to decay to a small value beyond the shock. Tests on one-dimensional shocks and a two-dimensional shock-bubble interaction confirm that the method gives good results. {\textcopyright} 1997 Academic Press.}, author = {Morris, J.
