WebNov 1, 2024 · The problem is formulated by the Rayleigh–Plesset dynamical equation, whose numerical solutions are carried out by Maple. Our studies show that each physical parameter affects the bubble collapse dynamics in different degree, which reveals that bubble collapse dynamics must considers all the parameters including liquid viscosity, … WebDifferent from Lin et al.‘s approach, we do not adopt the theoretical model optimized for modeling bubble (i.e., the Rayleigh-Plesset equation). Instead, we directly compute how bubble moves through numerical simulations of multiphase flow. Based on PINNs, ...
