DESIGN ASPECTS AND PERFORMANCE CHARACTERISTICS OF RADIAL FLOW ENERGY DISSIPATORS

THE RADIAL FLOW ENERGY DISSIPATOR INCORPORATED A VERTICALLY CURVED DROP SECTION WHICH INDUCED RADIAL SUPERCRITICAL FLOW IN A RAPIDLY FLARED BASIN WHERE AN ARC OF A CIRCULAR HYDRAULIC JUMP WAS FORMED. HIGH PRESSURES WERE DEVELOPED WHEN THE FLOW IMPINGED ON THE BEGINNING OF THE BASIN FLOOR, THUS FORCING THE FLOW TO SPREAD LATERALLY AND STAY IN CONTACT WITH THE FLARED WINGWALLS OF THE STILLING STRUCTURE. BASED ON THE EXPERIMENTAL RESULTS AND A SEMI-ANALYTICAL TREATMENT OF THE HYDRAULIC CHARACTERISTICS OF THE RADIAL FLOW BASIN, A DESIGN PROCEDURE WAS DEVELOPED WHICH MAY BE FOLLOWED FOR THE SELECTION OF THE IMPORTANT DIMENSIONS OF A RADIAL FLOW DISSIPATOR UNDER A GIVEN SET OF FIELD CONDITIONS. A SIMPLIFIED FORM OF THE CIRCULAR HYDRAULIC JUMP EQUATION WAS OBTAINED WHICH WAS THE BASIS FOR THE DESIGN PROCEDURE. /FHWA/
