Abstract
Our aim with this paper is to contribute to clarify the role played by the most commonly used WCSPH viscous terms in simulating viscous laminar flows. To achieve that, Takeda et al.¿s [1], Morris et al¿s [2] and Monaghan-Cleary- Gingold¿s [3], [4] viscous terms will be analyzed, discussing their origin, their structure and their conservation properties. Their performance will be monitored against canonical flows for which the viscosity related phenomena are well understood, and in which boundary effects have a relatively low relevance. One of the study cases has been a Lamb-Oseen vortex evolution for which both an exact solution and a finite-element numerical solution have been derived. The results of these tests confirm, those previously published. The SPH viscosity models behaviour in modelling the viscosity related effects for these canonical flows is adequate.
