A numerical technique for analysis of heat transfer and thermal distortion in reciprocating sliding components is proposed. In this paper we utilize the Arbitrary Lagrangian Eulerian (ALE) description where the mesh displacement can be controlled independently from the material displacement. A stationary and a moving component are modeled respectively as Lagrangian (mesh displacement equals material displacement) and Eulerian (mesh is fixed in space and material moves through the mesh). The description of the contact between both components accounts for frictional heating and heat exchange.
