dc.description.abstract | Chorin's random vortex method is used to predict the growth of a large-scale coherent vortex structure in the early stages of the development of turbulence in a two-dimensional co-flowing shear layer. The numerical algorithm has been simplified to such an extent that the numerical analysis can be performed on a microcomputer. The numerical solution exhibits the same early turbulent instabilities and vorticity pairings as found in recent flow-visualization experiments. In addition the results are in reasonable agreement with experimental measurements of mean velocity, root mean square fluctuations and Reynolds stresses. One could thus test the shear layer sensitivity to initial conditions and the upsteam boundary conditions. | en_US |

dc.contributor.affiliationum | Department of Mechanical Engineering and Applied Mechanics, The University of Michigan, Ann Arbor, Michigan, U.S.A. ; Jonathan Laitone was an Assistant Professor in Mechanical Engineering at the University of Michigan when he was killed, along with ten other young men, on 21 June 1981, in the worst mountain climbing accident in U.S. history. This occurred on Mt. Rainier near Seattle, Washington, when a huge portion of a glacier fell and was shattered into thousands of ice blocks. Among the eleven men who were killed instantly were two aeronautical engineers from England. Eighteen of the original climbing group miraculously survived. This manuscript was recently found when Jonathan's father was clearing out his son's files. Then Drs. Tzong-Hsi Chen and Michael Hooven, who as graduate students had worked with Jonathan on this project, were able to locate the computer print-outs. Finally, the manuscript was edited by Professor Antoni Oppenheim and Alexandre Chorin at the University of California, Berkeley, and Professor Ahmed Ghoniem at the Massachusetts Institute of Technology. | en_US |
