A NEW COMPUTATIONAL FLUID DYNAMICS STUDY OF A LIQUID-LIQUID
where t represents the time, ρ is the symbol of the fluid density, u shows the velocity of the fluid, P is the pressure of the system and finally f indicates the volume force exerted on the fluid. The two governing equations have to be solved concomitantly in order for the velocity and pressure distribution of the fluid inside a hydrocyclone to be obtained.
