DEPARTMENT OF COMPUTER SCIENCE UNIVERSITY OF WATERLOO SEMINAR ACTIVITIES NUMERICAL ANALYSIS SEMINAR - Monday, March 10, 1986. Dr. Ching Yuen (Ken) Loh of the National Research Coun- cil, Ottawa will speak on ``Numerical Techniques for Free Surface Problems in Viscous Incompressible Flows''. TIME: 2:30 PM ROOM: MC 6081F ABSTRACT Two typical free surface problems in viscous incompres- sible flows are considered. The governing Navier- Stokes equations are solved numerically together with the continuity equations for Reynold's number up to the order of 100, based on coordinate transformations and implicit Crank-Nicolson scheme as applied to the Navier-Stokes equation. For the free surface profile, a similar implicit scheme is used to replace the well known Lax-Wendroff scheme. Numerical results are satisfactory.
