Abstract EN

Regenerative pumps (RP) are one of the rotor-dynamic machine types that can develop high pressure head with a single impeller at low flowrates.

Researchers and manufacturers are driven to investigate the improvement of the head of the pump improvement using a various type of modifications, as the head of pump is one of the main effective parameters which indicates the performance of any operating pump.

These regenerative pumps are used in many fields of applications such as chemical, micro, bio, micro heat exchangers, etc.

Therefore, a lot of researches examined the effect of different possible design modifications on the head of the RP.

Changing one of the angles of the blades (inclination or chevron angles) was found to have a significant impact on the performance of the pump compared to the standard pump with zero angles blade.

This present research provides an eminent head enhancement for the RP by using a suitable combination of blade angles modification.

This enhancement is obtained numerically using ANSYS-CFX 19.1 software, after validating the new model by comparing the simulation results with the available published experimental ones.

The suggested modification applied is the double forward impeller, DFB, with chevron angle α=+15o and inclination angle β=+15o.

An increase in the performance of this type of pumps at the tested conditions by 40 % in head is acquired compared with that of the standard pump.
