Abstract
Chemically reactive and nonreactive hydrodynamics around rotating porous spheres with surface blowing in a stagnant environment, as well as that of a stationary droplet in counterflow counter-rotating jets was theoretically and experimentally investigated. Stream functions were presented describing spherical flows formed from two, four, and six toroidal vortices. Such flow fields were identified as solutions of the viscous vorticity equation. One stream function follows Hill's solution for spherical vortex and describes internal cylindrical flows formed by line vortices and cascades of concentric spherical and cylindrical flows. Such flow dields are important to the modelling of local hydrodynamics and dissipative processes within turbulent sprays.
