gas motion within the cylinder is one of the major factors that control the combustion process in spark ignition engine. it also has significant impact on heat transfer. both the bulk gas motion and the turbulence characteristics of the flow are important and governing the overall behavior of the flow. an arrangement for obtaining a stratified charge, using port injection, is proposed for a cur...

This paper presents a novel formulation for the computational homogenization analysis of materials at limit state. The polynomial interpolations are employed to impose periodic boundary conditions fluctuating term displacement field when using arbitrary finite element meshes. Second-order cone programming provides an efficient solution solve resulting optimization problems, and accurate load mu...
