In industrial production，there are often a variety of liquids between the injection behavior，and in the fluid miscibility phenomenon，due to the fluid molecules at the interface out of the main body of the internal force situation is different，resulting in the interface at the interface of the fluid has a different fluid properties than the fluid inside．One of the most obvious phenomena is the Magorani effect，which is manifested by the fact that the particles at the interface of the fluid below will flow counter currently along the water flow in the process of the fluid injection above． Therefore，this paper is a parameterized simulation study of this phenomenon．Based on the COMSOL simulation software，different dimensions of the " upstream pollution phenomenon" are simulated，and the simulation model of particle and fluid is constructed to parameterize the four variables，namely，particle mass，fluid temperature，injection height，and surface tension，and to investigate the effects of different parameters on the particle counter current phenomenon．
