Abstract

In the present study, the effect of outlet opening location on providing appropriate and uniform thermal conditions and distribution of carbon dioxide species which is produced by high temperature radiant heaters under nonuniform flow field in an industrial environment have been investigated. For this reason, two dimentional environment with one inlet and one outlet opening have been considered. Two locations of air outlet opening near the floor and near the ceiling and also, two different types of radiant heaters’ arrangement have been considered as: single radiant heater, couple radiant heaters. For the mentioned conditions, continuity equation, momentum equations, energy equation, radiative transfer equation and species concentration equation have been solved by OpenFoam numerical solver. Also energy consumption have been evaluated in the present study. The results show that location of air outlet opening near the ceiling effects significantly on decreasing carbon dioxide concentration. As well as, usage of couple radiant heaters makes temperature distribution more uniform. The results indicate that energy consumption increases in presence of couple radiant heaters for outlet opening which is near the floor 3 percent and near the ceiling 15 percent in comparison with single radiant heater.
