Paper presented to the 10th International Conference on Heat Transfer, Fluid Mechanics and Thermodynamics, Florida, 14-16 July 2014.
A numerical investigation to determine the thermal
characteristics of an unsubmerged axisymmetric oil jet
impinging in a confined space on both stationary and high
speed reciprocated moving discs with uniform heat flux has
been undertaken. 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.
