Description
Summary:A detailed GPU-based parameter study is performed on the nonlinear shape deformation of acoustically excited bubbles using a second-order perturbation theory developed by Shaw (2006). The parameter scan is utilized for an extensive validation study based on a detailed measurement study conducted by Cleve et al. (2019). Out of the ten measurements, six exhibit an excellent match with the simulation results. For the discrepancies of the remaining four, the authors identified two causes. First, the parameter identification of the measurement is prone to significant error; second, the dynamics of the surface wave oscillation is out of the validity limit of the employed model. [Display omitted] •A GPU-based extensive parameter study with measurement comparison.•The validity limit of the nonlinear method developed by S. J. Shaw is approximated.•Incidental errors in parameter identification were found.
