Abstract
A numerical simulation has been made of the combined stroke swimmer (a deformable sphere) and compared with the results of the second-order perturbation theory of Felderhof and Jones (2017). At a small ratio of the amplitude of the deformation of the sphere and the radius of the sphere the numerical and theoretical results agree well. However for a larger value of this ratio the results deviate due to inertia. The streamlines, as calculated numerically, change significantly with increasing inertia.
