Annual review of fluid mechanics. Volume 19

The present evaluation of the status of fluid mechanical research gives attention to confined vortices in flow machinery, turbulent secondary flows, upstream blocking and airflow over mountains, critical point concept descriptions of eddying motions and flow patterns, viscoelastic flows through contractions, the theory of solute transport by groundwater, tsunamis, turbulent premixed flame behavior, and viscous fingering in porous media. Also treated are the computation of flows with shocks, the use of spectral methods in fluid dynamics, the dynamics of tornadic thunderstorms, thermocapillary instabilities, the behavior of magnetic fluids, Von Karman swirling flows, the use of isolated eddy models in geophysics, recent developments in rapid distortion theory, and rarefaction waves in liquid and gas-liquid media
