Molecular cavity flow

Using molecular mechanics, cavity flow is studied in a basin of 4235 water molecules at 15 degrees C. Primary vortices are generated with wall speeds V = -20, -40, -100, -250 Angstrom/ps. The vortex motions agree with experim ental results in the large. Fully turbulent flow is generated with wall spe ed V = -3000 Angstrom/ps. The mechanisms for primary vortex generation are clearly delineated, as are those for turbulent flow. (C) 1999 The Japan Soc iety of Fluid Mechanics and Elsevier Science B.V. All rights reserved.
