Description: Miscellaneous Paper
Abstract: A method has been developed for computing two-dimensional pressure distributions inside hydraulic structures. Velocities are first obtained by finite difference solution of the Navier-Stokes equations in stream-function/vorticity form. Pressure is then calculated by numerical integration of the momentum equation. The method has been incorporated for arbitrary geometry in the VORTEX computer code, which uses boundary-fitted grids generated by the WESCOR code. Computed results compare well with piezometric data from physical-model tests for the Taylorsville outlet works, indicating that the VORTEX code may be useful in identifying and eliminating flow conditions that promote cavitation.
