Radiation Heat Transfer Modelling with Computational Fluid Dynamics serves as a reference for principles of thermal radiation and its modelling in computational fluid dynamics (CFD) simulations. It covers computational techniques for solving the Radiative Transfer Equation and strengths and weaknesses thereof.

Über den Autor / die Autorin
Yehuda Sinai qualified in Mechanical Engineering at Witwatersrand University (South Africa) in 1968. He obtained a PhD in Aerodynamics at Cranfield University in 1975, on non-equilibrium molecular relaxation effects in sonic booms. After a spell in academia, working on acoustics and two-phase fluid-structure vibrations, on contract for the US Navy and the British Admiralty, he spent 10 years at NNC (National Nuclear Corporation Ltd.), principally on mathematical modelling of nuclear safety thermal-hydraulics. He joined AEA Technology in 1992, where he specialised in CFD (Computational Fluid Dynamics) modelling in the safety sphere, and became CFD Project Manager for Fire, Safety, HVAC and Environment. This role continued after the acquisition of AEA's CFD operation by ANSYS Inc. in 2003. In July 2009, Yehuda set up his own company, HeatAndFlow Consultancy Ltd., offering general modelling but with a focus on CFD tools. He has authored and co-authored approximately 60 scientific papers in archival journals and conference proceedings and is the author of a chapter in a technical encyclopedia.
