Monte Carlo Simulations of Radiative Heat Transfer with Parallel Computer Architectures

This paper covers the development of a method based on classical probability distribution function and random numbers to evolve a computer algorithm for determination of total exchange areas in three dimensional furnace enclosures with emitting and absorbing surfaces. The method involves simulation of the pathways of a large number of beams carrying finite amount of energy from a specified surface zone inside an enclosure and tracing their routes until they get absorbed.

Equations for beam tracings and intersection criteria have been developed for plane walls, rectangular paralleopiped and cylinders.

Computed total exchange areas were found to be within 0. The equations once verified can be applied to more complicated geometries by combining these basic shapes using zone method. Total exchange areas thus obtained can then be used in heat balance equations for multiple surface and gas zones to find the temperature and heat flux profile inside the furnace enclosure.

These will be especially useful in modelling and simulation of reaction furnaces of unconventional shapes. Authors: Parthasarathy, G.

The calculated temperature profiles are then used as thermal boundary conditions in simulations of rarefied gas flows in the LPCVD reactor. The thermal variations along the quartz and wafer surfaces give rise to significant temperature and density variations in the gas flow. The simulation results show excellent agreement with experimental data.
