Abstract

A numerical analysis for the irreversible process in an adiabatic piston-cylinder system has been conducted. Two-dimensional compressible momentum and energy equations were solved numerically to obtain the state quantities of the system using the laminar flow model. The numerical method is based on the combined Implicit Continuous-fluid Eulerian technique and the Arbitrary-Lagrangian-Eulerian method. The computations were performed for a single compression process with the piston velocity of -10 m/s for the effect of diameter cylinder, Dwhich are 0.02 m, 0.04 m and 0.06 m. We found that, size of the diameter cylinder has an effect to the occurrence of the irreversible process. Increase the size of diameter of the cylinder will resulting to the increases of the average pressure on the piston surface, in the cylinder. The average value of during the compression process for the case of the D= 0.02 m, 0.04 m and 0.06 m are 1.00026, 1.00042, and 1.00057, respectively.
