Abstract

This study consists of two parts one aims at incorporating radiation effects of wall in partial enclosure and another being the analysis of train re with the help of Fire Dynamics Simulator. The flow situation is two dimensional, turbulent natural convection flow. The flow is studied using stream function and vorticity formulation approach with radiation thermal boundary condition. Conventionally in a given flow situation the boundary conditions are assumed to be adiabatic but the radiation by walls and heat source affects the flow field and temperature field considerably. This study is an attempt to consider the radiation effects and get more realistic results. The computer programming being used to implement the radiation effects is FORTRAN.
