DESCRIPTION:Bondi-Hoyle-Lyttleton accretion is the flow of a uniform fluid
  onto a compact object moving at constant velocity. Although some aspects 
 of the flow can be derived analytically\, it is necessary to perform numer
 ical \nsimulations in order to obtain a full flow analysis. I shall discus
 s previous simulation results in this area\, in the cases of a non-uniform
  fluid and of axisymmetric or thin-disc accretion onto a black hole. I wil
 l explain the numerical and computational approaches required to simulate 
 the case of fully three-dimensional relativistic Bondi-Hoyle-Lyttleton acc
 retion of a non-uniform fluid onto a spinning black hole. I will then pres
 ent the results of a parametric study performed using these techniques\, v
 arying the spin of the black hole\, the accretion direction\, and the flui
 d density profile\, and conclude with an analysis of some aspects of the f
 low.\n
