Combined Effect of Fluid Cavitation and Inertia on the Pressure Buildup of Parallel Textured Surfaces

A mathematical model is developed to investigate the combined effect of fluid cavitation and inertia on pressure buildup parallel textured surfaces. The analyzed using Rayleigh–Plesset model, with an averaged method. finite element method Newton-downhill are employed solve governing equations. numerical validated by comparing experimental results, discussed. research indicates that weakens distribution at inlet area textures. greatly enhances hydrodynamic effectively limits excessive extension low-pressure zone caused cavitation. inertia, especially their interaction, significantly affect generate a net load-carrying capacity (LCC). more time saving than commercial CFD tools in solutions, which gives novel optional HD foundation for developing efficient accurate THD or TEHD programming.
