Influence of physical parameters on the collapse of a spherical bubble

• Examined the influence of physical parameters on the collapse dynamics of a spherical bubble filled with diatomic gas ( k = 7 / 5 ). • Shown that each physical parameter affects the bubble collapse dynamics in different degree. • Studied bubble dynamics phase diagram for the first time. • Provided a Maple code for spherical bubble collapse. This paper examines the influence of physical parameters on the collapse dynamics of a spherical bubble filled with diatomic gas ( κ = 7 / 5 ). 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, surface tension, etc, else the outcome cannot be trusted.
