This uses a third-order (in time) scheme from Daitsche (2013). The equations solved are a rewritten version of the Maxey-Riley equations, sans the Faxen correction terms.
and
where is the particle location, is the difference between the particle velocity and the fluid velocity , is the 'velocity term' (the part of the Maxey-Riley equation corresponding to the instantaneous effects of the local fluid flow), and is the 'history term'. The velocity term is given by
and the history term by
