چکیده: Abstract: In this research, a centrifugal pump has been analyzed until the changes in its blade thickness, the change in the rotational speed of the blades and the change in the speed of the incoming flow have been analyzed. And its effects should be investigated especially on the pressure distribution in the pump and on the blades. For this reason, Ansys Fluent software was used for simulation and the introduction of the main governing equations and a detailed explanation of how the simulation is done in the software And then the results are presented and discussed in the form of contours and graphs. A total of 15 simulations were performed with three variables in this pump, in which the width (thickness) of the vane, the rotation speed of the propeller and the water inlet speed were changed. Each of these variables took three values in simulations one to nine, blade thickness was constant and equal to 7 mm, and rotational speed and fluid inlet speed were changed. In simulations number one to three, the rotational speed was equal to 2160, in simulations 4 to 6, the rotational speed was 3240, and in simulations 7 to 9, the rotational speed was 4320 rpm
