The creeping motion of a spheroidal particle at the instant it passes the centre of a spherical container has been examined using a general slip condition at the surface of the particle. The shape of the spheroid deviates slightly from that of a sphere at its surface. A first‐order expression has been obtained for the stream function characterizing the flow field and this expression has been utilized to evaluate the drag on the spheroid. Special cases are deduced and wall effects then examined.
