The effects of a magnetic gradient on lifted diffusion flames

Reducing pollution and increasing energy efficiency are two tests extensive studies for combustion. methane is a fuel of choice; it releases a large amount of heat and its molecular simplicity allows it to produce less pollutants. in many systems,the use of methane combustion takes place by diffusion flame. in the present paper,we developed impact of a magnetic field gradient to develop a laminar flame with an axisymmetric actuator ch4/air. results are explained by the effects of magnetic force,and thermo magnetic convection which involves the thermal variation of magnetic susceptibility. the gradient of a magnetic field reduces the air velocity and the spatial gradient of the mass fraction of methane,which are important effects of reducing the lift-offheight and increasing the propagation flame velocity. © 2015 jordan journal of mechanical and industrial engineering.
