Friction Temperature of the Piston Rings with Consideration of the Cylinder Wall Thickness 2004-01-0612

Analysis of the friction temperature of a piston ring in a reciprocating oil-less compressor was presented in the work of V. Dunaevsky and I. Kudish published in 1998 by SAE, Paper 982828. In that work a theoretical analysis of the transient friction temperature at the interface was conducted under a simplifying assumption that the ring slides over the plane which serves as the boundary of a half-space with infinite thickness. In the current paper the simplifying assumption that the cylinder wall has infinite thickness is replaced by the assumption that the wall thickness is finite, i.e. by a finite thickness layer bounded by two parallel planes. A numerical heat transfer model was used to show effects of wall thickness and heat transfer coefficient on transient and steady temperature distribution across the wall.
