Flow Boiling in an Asymmetrically Heated Single Rectangular Microchannel

ANALYSIS OF COMBINED CONDUCTION AND RADIATION HEAT TRANSFER IN A RECTANGULAR FURNACE INCLUDING TWO FLAMES

Abstract: The present study deals the theoretical modeling aspects of coupled conductive and radiative heat transfer in the presence of absorbing, emitting and scattering gray medium within two-dimensional square furnace including two flames. The gray radiative medium is bounded by isothermal walls which are considered to be opaque, diffuse and gray. The well known discrete ordinate method (DOM...

Numerical analysis of supercritical flow instabilities in a natural circulation loop

Numerical studies have been carried out to investigate flow instabilities in a natural circulation loop with supercritical CO2. For steady-state and dynamic analyses of the loop under supercritical conditions, a single-channel, one-dimensional model is developed. In this model, equations for the conservation of mass, momentum and energy are discretized using an implicit finite difference scheme...

Natural Convection at Different Prandtl Numbers in Rectangular Cavities with a Fin on the Cold Wall

The natural convection in differentially heated rectangular cavities with a fin attached to the cold wall was investigated numerically. The top and the bottom horizontal walls of the cavities were insulated while their left and the right vertical walls were maintained at a constant temperature Th and Tc, respectively with Th > Tc. The governing equations written in terms of the primitive variab...

A Compile-Time Partitioning Strategy for Non-Rectangular Loop Nests

This paper presents a compile-time scheme for partitioning non-rectangular loop nests which consist of inner loops whose bounds depend on the index of the outermost, parallel loop. The minimisation of load imbalance, on the basis of symbolic cost estimates, is considered the main objective; however, options which may increase other sources of overhead are avoided. Experimental results on a virt...
