DESCRIPTION:_We consider a collection of N solid particles immersed in a B
 rinkman liquid and subject to an external flow and/or a uniform gravity fi
 eld.  It is shown how to reduce the determination of the unknown rigid-mot
 ion of the particles by solely calculating a few and carefully selected qu
 antities on the surface of the entire cluster.  Those key quantities are g
 overned by boundary-integral equations which are established and numerical
 ly solved by implementing a boundary element method.  Numerical results wi
 ll be discussed for a few 2-particle clusters in order to quantify the mag
 nitude of particle-particle interactions in a suspension._
