Validation of Numerical Model for Cook Stove using Reynolds averaged Navier-Stokes based Solver

Rio mass fired acook stoves, for many years, have been he main cooking appliance for the rural people of developing countries. Several researches have been carded out to the find efficient stoves. In the present study, numerical model of an improved household cook stove is developed to analyze the heat transfer and now behavior of gas during operation. The numerical model is validated with the experimental results. Computation of the numerical model is executed the using non-premixed combustion model. Reynold's averaged Navier-Stokes (RaNS) equation along with the kappa - epsilon model governed the turbulent flow associated within the computed domain, The computational results are in well agreement with the experiment, Developed numerical model can he used to predict the effect of different biomasses on the efficiency of the cook stove,
