Abstract

A deformable body immersed in a randomly stirred incommpresible fluid was analyzed. The deformation of the body was investigated, sticking to physical situations in which the body departs only slightly from its spherical shape. The correlations of spherical harmonic modes for a general class of random flows that include, the flow due to thermal agitation, were studied. The results are applicable to a large class of deformable bodies with energy that depends only on the shape of the body, and a general class of random flows.
