Abstract

In order to study the effects of high intensity acoustic fields on heat and mass transfer around spherical particles, a two dimensional, unsteady computer code which employs the two dimensional, unsteady conservation of mass, momentum and energy equations for laminar flow in spherical coordinates has been developed. Numerical solutions of these equations give the dimensionless temperature and velocity fields around the particle for acoustically oscillating flows with and without superposed steady flow as a function of dimensionless time, acoustic Reynolds number, Strouhal number, and the ratio of the acoustic velocity to the steady slip velocity between the particles and the main flow. The results demonstrate a definite enhancement of heat and mass transfer in the presence of high intensity acoustic fields particularly for the case of a low steady slip velocity.
