Im interested in the “structures” (streamlines) formed in fluid media by the action of internal/external forces and how they affect the relevant transport phenomena. The figures below show the streamlines and velocities formed in different setups that I have been interested on; (top, from left to right): experimental streamlines formed behind a bubble rising in a complex fluid showing a negative wake. The figure at the right shows instantaneous streamlines formed by an oscillating flexible flapper: shift of the vortex center is the key factor to understand the net pumping produced by this device. (bottom, from left to right): theoretical streamlines formed by ciliated carpets immersed in mucus (non-Newtonian shear-thinning fluids); the figure at the right shows the liquid velocity magnitude produced by the rise of several bubbles, a numerical code was used in this case.
