Abstract

The influence of magnetic field on combustion has attracted many researchers. Since the effect of the magnetic field on the gas flow and the combustion process is through volumetric electromagnetic force, the need for a numerical solution and electromagnetic simulation of the flow field is necessary to obtain the distribution of the magnetic field. The present study investigates the numerical variations in the shape and temperature of the diffusion flame of methane in the presence of a non-uniform magnetic field. For this purpose, two groups of electromagnetic equations and fluid mechanics and combustion are solved simultaneously. The results show that magnetic force volumetric influences on paramagnetic (oxygen, air) and diamagnetism (methane and combustion products) effects on flame shape, flame temperature, and mixing of fuel and air. Also, the use of a decreasing magnetic field causes Slim and drawn flame shape and increase flame temperature and the application of an increasing magnetic field causes the shape of flame to be shortened and diffused (Mushroom-shaped) and the flame temperature decreases relative to the non-magnetic field.
