Transient response of a participating medium subjected to short pulse radiation sources

Abstract

Thermal radiation is important in many areas such as internal combustion engines boilers furnaces solar collectors reentry vehicles remote sensing bio medical imaging and surgery Its propagation speed in vacuum is 3x10x8 m s In many heat transfer problems involving thermal radiation in which temporal information is sought at time levels above micro seconds radiative transfer is essentially an instantaneous process and thus the time dependent term in the governing radiative transfer equa
