Abstract

This project present an investigation of flame stabilization in counter current micro combustors. The stabilizing a flame inside a micro combustors poses a great challenge to researchers. This Final Year Project focuses mainly on the designing the numerical model for simulations to investigate effect of counter current flow on the flame stabilization in counter current micro combustor with stainless wire mesh. In the counter current combustors, a portion of the tube was heated exhaust gas coming from the burned gas region. Flame stabilization limits were then determined. The flame stabilization limits in this case is defined as the limits in which the flame stabilizers near to the wire mesh of the tube counter current combustors. Investigation of the numerical models with different combinations were performed to deduce the trend pattern of the gas temperature. From the result of the simulations, it can be deduced that higher wall temperature in the burned gas region contributes to better flame stabilization limits. The effective role of the wire mesh in distributing heat from the burned to the unburned gas region was demonstrated by using the developed 3-D numerical simulation. The result from the simulations are then utilized to propose a combustors that can be used for both gaseous and liquid fuels.
