Lack of proper ventilation exhaust fumes from gas fired stoves in residential kitchens is a major health concern for some populations. It could even cause destruction property, and reduce quality life lifespan. In this study, typical kitchen having standard dimension 2.13 m × 2.43 3.05 was modeled with single open door exit. Two heat sources were used modeling the that resembles double burner stove an urban developing countries. Steady-state simulations performed using three-dimensional computational fluid dynamics (cfd) code appropriate boundary conditions. The present numerical method validated by comparing experimental data reported Posner et al. (2003, “Measurement Prediction Indoor Air Flow Model Room,” J. Energy Build., 35(5), pp. 515–526). comparison showed very reasonable agreement. A grid independence test also to determine optimum resolution reflecting accuracy solution. results are presented carbon dioxide (CO2) emission dispersion within space. comparative analysis between (natural forced) no conditions study. location breathing zone at height 73 cm distance 33 center two burners.

As per Wisconsin Department Health Services USA, over ppm exposures lead oxygen deficit resulting permanent brain damage, coma, death.
