Discussion

CFD simulation revealed critical speed impacts cavitation in two-dimensional electro-hydraulic pump, suggesting design optimizations.

Cavitation intensity is influenced by critical speed and suction pressure in the two-dimensional electro-hydraulic pump, with higher speeds worsening cavitation.
Gas volume fraction is a key indicator of cavitation location and intensity, particularly in the plunger chamber and distribution groove.
CFD numerical modeling across varying operational conditions clarifies the relationship between suction pressure and cavitation development.
Implications for pump design highlight the need for optimization to mitigate cavitation effects during high-speed operation.

A 2025 study studied this question.
