WAVE DAMPING EFFECTS OF SCREENS; HYDRAULIC MODEL INVESTIGATION.

Abstract

An expression is derived for the damping of translation waves by screen filters in terms of filter extent and length of wave. Derivation involves the resistance coefficient of screens; and tests show that this term cannot be derived from the known resistance law of circular cylinders but must be determined for a particular screen for the condition of steady flow. Observed damping and computed damping agree fairly well. Results are extended intuitively to the case of surface waves. The analysis is compared with the Goda-Ippen theory of screen filters to establish the conditions for the equivalency of results in these two approaches. (Author)
