“…Cavitation bubbles are formed in the low-pressure area; then, they follow the flow in the direction of the pump exit, collapsing in the high-pressure area [ 108 ]. Cavitation erosion is considered during the pump selection, and the net positive suction head available ( NPSHa ) can be expressed by

P ab is the absolute pressure, P v is the vapor pressure of the liquid, ρ is the liquid density, and g is the gravity acceleration [ 109 ]. The net positive suction head required ( NPSHr ) is the minimum pressure of the pump to prevent cavitation.…”

The cavitation erosion failure of pumps or valves induces the low efficiency and reduced service life of nuclear reactors. This paper reviews works regarding the cavitation erosion of pumps and valves in the nuclear power industry and academic research field. The cavitation erosion mechanisms of materials of pumps and valves are related to the microstructure and mechanical properties of the surface layer. The cavitation erosion resistance of austenitic stainless steel can be ten times higher than that of ferritic steel. The cavitation erosion of materials is related to the hardness, toughness, and martensitic transformation capacity. Erosion wear and erosion–corrosion research is also reviewed. Erosion wear is mainly influenced by the hardness of the material surface. Erosion–corrosion behavior is closely connected with the element composition. Measures for improving the cavitation erosion of pumps and valves are summarized in this paper. The cavitation erosion resistance of metallic materials can be enhanced by adding elements and coatings. Adhesion, inclusion content, and residual stress impact the cavitation erosion of materials with coatings.

The aim of the current study is to examine the impact of the ogive radius of a 7.62x39 ammunition projectile on the positioning of a radially-slotted channel that helps increase the angle of the cavitation cavity. The studies were conducted using CFD (Computational Fluid Dynamics) analyses in a SolidWorks environment, simulating the projectile's movement in a water environment. The research findings indicate that lower values of the ogive radius result in higher values of the cavitation cavity angle, which in turn suggests that lower values are more favorable for creating bullets with slotted channels, which enhances linear-progressive movement in a water environment and thus increases the chance of hitting targets below sea level.
