text: Here we give the flow field of a squirmer in the case of a non-deformable axisymmetric spherical squirmer (radius ). These expressions are given in a spherical coordinate system.
  <br />
  Here  are constant coefficients,  are Legendre polynomials, and . <br />
  One finds .<br />
  The expressions above are in the frame of the moving particle. At the interface one finds  and .
