An acoustic cavitation model for noncondensable gas/vapor bubbles that couples spherical bubble dynamics by the Keller-Miksis equation to the Plesset-Zwick equation is constructed by accounting for phase change, but neglecting the mass diffusion of the noncondensable gas. Results obtained for acoustically driven air/water-vapor cavitation bubbles using two different acoustic pressure signals and variable fluid properties show reasonable agreement with the reduced order model of Preston et al.
