AbstractThe paper presents results of numerical analysis of fluid flow in the axial pump for thermoregulation systems of aircraft. There are the features of the flow of coolant in the pump at different operation modes. It was found that the pump operation at low flow rate accompanied by significant and intense reverse flow and separation effects, while varying the angle at the entrance to the impeller geometry can minimize the identified effects.
