Hydrodynamics and Heat Transfer of Cavitation Bubble in Nanoparticles/Water Nanofluids Based on the Effects of Variable Surface Tension and Viscous Forces

The aim of the present work is to focus on the cavitation bubble dynamics while considering the impact of the variable surface tension and viscous forces in Newtonian mono-nanomaterials in many kinds of appropriate particles (i.e., copper -oxide, titanium -dioxide, disulfide -molybdenum) with water nanofluids, which have been utilized to investigate industrial processes. This study proposes cavitation bubble dynamics in viscous, superIP: 203.8.109.20 On: Tue, 16 Apr 2024 14:29:32 heated liquid, and nanoparticles/water nanofluid. The mathematical model is formulated via thermophysicalCopyright: American Scientific Publishers configurations of nanoparticles (NPs), mass, momentum, and energy equations in nanofluids. This paper Delivered by Ingenta explains how cavitation bubble growth in superheated nanofluids is critical for the power values n on which it is highly dependent. It's been found that the behaviour of cavitation radius, variable surface tension and viscosity in NPs/water nanofluids is inversely proportional to the volume NPs concentration. Cavitation bubbles behave differently in water than in NPs/water nanofluids. The rate of the growth process increases with lower values of NPs diameter, so the influence of size NPs can regulate and control the cavitation bubble dynamics. Ultimately, a comparison between the current model and some previous models is investigated, showing the compatibility and consistency between the proposed and published models.
