MishraThermal 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 equation is neglected.enMECHANICAL ENGINEERINGMECHANICAL ENGINEERINGThesis
