A squirmer is an idealized spherical <microswimmer> propelled by a prescribed tangential <surface slip velocity>. The <Lorentz reciprocal theorem for Stokes flow> determines its rigid translation and rotation without solving its complete exterior flow.

A microswimmer is a microscopic body that propels itself through a fluid. At small <Reynolds number> its motion is governed by <Stokes flow>, and self-propulsion must respect the <force-free> and <torque-free> conditions.
