Abstract

The work presented in this paper focuses on the effect of jet pulsation on the heat transfer and fluid dynamics characteristics of single and double jet impingement on a constant heat flux heated surface. Specifically, the influence of frequency, amplitude and in particular, of the phase difference of the two jets on the temperature distribution of the heated surface is examined. The simulations are conducted using a novel, remeshed Smooth Particle Hydrodynamics (SPH) methodology that is based on particle discretization of the governing compressible Navier-Stokes equations. It was found that the strong aerodynamic and thermal interaction that exists between the gaseous jets and the impingement surface leads to non-linear system responses; with serious heat transfer implications. Dynamical systems analysis leads to the identification of intermittent periodic/chaotic behavior above a threshold value of the Reynolds number. As a result, a reduction in the maximum plate temperature in a window of periodic behavior was discovered.
