Energy is unarguably the key factor for today's economic and social development within
nations. Electricity as one of many energy forms is a critical input to developing countries in …

Erosion wear of the centrifugal pump components is considered one of the principal hurdles
for pumping and transporting the particle-fluid flow in the hydraulic system. Although the …

In this study, we proposed a novel approach to improve centrifugal pump performance with
regard to the pump head, pump efficiency, and power. Firstly, to establish constraints, an …

An investigation is presented on the unsteady flow behaviour near the tongue region of a
single-suction volute-type centrifugal pump with a specific speed of 0.47. For this study, the …

The flow analysis inside the centrifugal pump is highly complex mainly due to 3D flow
structure involving turbulence, secondary flow, cavitation and unsteadiness. In recent years …

Hydropower represented in 1999 19% of the world electricity production and the absolute
production is expected to grow considerably during the next 30 years. Francis turbines play …

Computational fluid dynamics (CFD) has been widely used to model the internal flow field of
centrifugal pumps to analyze cavitation phenomena. However, accurate determination of …

Computational fluid dynamics (CFD) analysis has been used to solve the unsteady three-
dimensional viscous flow in the entire impeller and volute casing of a centrifugal pump. The …

The operation of centrifugal pumps can generate instabilities and pressure pulsations that
may be detrimental to the integrity and performance of the pump. In the present study a …

The pump design is facilitated by the development of computational fluid dynamics and the
complex internal flows in water pump impellers can be well predicted. Various parameters …
