Abstract: The flow field around a cylindrical torsional resonator can be modelled analytically, but more complex shapes require more rigorous approaches. This study proposes a numerical model of a non-cylindrical torsional resonator for a viscosity–density measurement application. The proposed model couples an analytical mechanical model of the resonator with an empirical, simulation-based fluid model. The model was validated using experimental data over a wide range of fluid viscosities and densities. The predictions are in good agreement with the numerical model. The model could capture all viscosity- and density-related effects. Therefore, it will, enable computationally supported geometrical optimization of future viscosity-density sensors generations.
