Abstract:Phenomenon of flame acceleration of premixed combustible air-acetylene mixture towards the open end of adiabatic microchannel has been studied by solving Navier-Stokes (NS) system of equations with single step chemistry model. A two dimensional unsteady reactive NS solver has been developed using modified upwind splitting methods (AUSM+) and second order Runge-Kutta method to achieve the unsteady solutions. The predicted mechanism of flame acceleration, flame propagation speed and maximum outflow velocities are well in agreement with the conclusion drawn in the available literature related to the maximum flame acceleration configuration of the adiabatic microchannel.
