Computational modelling of cook-stoves

Abstract

Combustion inside a cooking stove is complicated to understand and describe. The process is highly dependant on the inlet conditions, fuel used and the geometry of the stove. It is very difficult to predict the distributions of temperature, velocity and product concentrations within the stove. The variation of stove efficiency with respect to boundary conditions is also unknown. The shortcomings have resulted in two major issues; namely, low overall stove efficiency and high emission levels. Computational modelling of the flow field and chemical reactions is a viable method to understand the combustion process in a cooking stove.
