The volume of fluid (VOF) method utilizing a high resolution interface capturing (HRIC) scheme was used to perform the two-phase (air-liquid) simulations. The governing 3D Navier-Stokes equations and energy equation were solved using a finite volume discretization. The conjugate heat transfer (CHT) method was used to obtain a coupled heat transfer solution between the solid and fluid, yielding a more accurate prediction for the heat transfer coefficient. A piston motion equation is used to provide a reciprocating motion for the disc inside a confined cylindrical space.7 pagesPDF© 2014 University of Pretoria. All rights reserved.
