✦ Synopsis

This paper presents a numerical strategy based on the ®nite element method for solving unsteady ¯ows without combustion inside an operating engine cylinder. A compressible ¯ow solver that can withstand highly distorted elements is presented. A robust mesh deformation procedure capable of handling the large valve and piston motions and deforming the unstructured mesh accordingly is then described. Turbulence is added through a one-equation model. The proposed strategy is applied to a three-dimensional realistic problem. Results are presented for the exhaust, intake and compression strokes of the cylinder operation.

The numerical modeling of the steady flow of a yield stress fluid around a cylinder is presented. Three categories of yielded regions are exhibited. The asymptotic behavior when the cylinder gets close to the wall is investigated. The resolution of variational inequalities describing the flow is bas
