The present problem simulates the cavitation phenomenon inside a radial flow pump using ANSYS Fluent software. This pump is of the centrifugal pump (radial flow) type; In this way, the desired fluid enters it parallel to the central axis and exits it radially or perpendicular to the inlet path. These types of pumps are commonly used to create high pressures at low flow rates and are also the most common type among pumps. The working fluid used in this pump is liquid diesel; Thus, it has a density equal to 830 kg.m-3 and a viscosity equal to 0.00332 kg.m-1.s-1.
Since pumps are devices that work inherently based on pressure changes, in this modeling, the pressure boundary condition at the inlet and outlet boundaries of the pump is used. Thus, the liquid diesel flow enters the pump axially with a pressure of 0 pascal and exits it radially with a pressure of 109872 pascal. Also, to define the rotation of the fluid inside the pump, a frame motion tool with a rotational speed equal to 20 rad.s-1 has been used. T
