Abstract:

A channel model using a finite-difference, gridpoint method is described in this report. Integrations with this model produre large amplitude, high wavenumber noise near the lateral walls which corrupts the interior solution. A technique is presented that employs scale-dependent filters to eliminate the generation of the boundary noise, yet to leave the interior flow relatively unchanged. The effectiveness of the technique is demonstrated. Author
