      A note on the unbounded creeping flow past a sphere for Newtonian fluids with pressure-dependent viscosity 

      Housiadas, Kostas D.; Georgiou, Georgios C.; Tanner, R. I. (2015)
      We investigate theoretically isothermal, incompressible, creeping Newtonian flows past a sphere, under the assumption that the shear viscosity is pressure-dependent, varying either linearly or exponentially with pressure. ...
