Experimental Investigation and Passive Flow Control of a
Passive flow control techniques are used to improve the flow field and efficiency of centrifugal pumps and turbomachines, in general. An important phenomenon that mechanical engineers have to take into account is cavitation. It leads to the decrease of the pump performance and total head. In the present experimental study, a centrifugal pump is investigated in cavitating conditions.

Experimental and numerical investigations on pressure
Apr 22, 2019· When a centrifugal pump runs as a turbine, high pressure fluid enters the machine and then leaves after the conversion of the energy, but in pump mode the rotating impeller increases the angular momentum by imparting energy on the flow, thereby increasing the pressure at the outlet. 2 Figure 1 shows a typical PAT operating in the pump mode.

Useful information on centrifugal pumps
Useful information on centrifugal pumps What is a centrifugal pump? A centrifugal pump is a mechanical device designed to move a fluid by means of the transfer of rotational energy from one or more driven rotors, called impellers. Fluid enters the rapidly rotating impeller along its axis and is cast out by centrifugal force along its circumference through the impellers vane tips.
