Run title and other preliminaries DISPLAY The case considered is laminar Couette flow between infinite parallel plane plates with heat transfer. The upper plate moves horizontally, while the lower plate remains stationary. The lower and upper plates are kept at uniform temperatures Tbot and Ttop, respectively. This problem is of practical interest in journal-bearing technology. ENDDIS ************************************************************ Group 1.
