HYDRAULIC JUMP WITHIN GRADUALLY EXPANDING CHANNEL

THIS EXPANDING CHANNEL JUMP IS CONSIDERED TO BEHAVE AS A SECTION OF A CIRCULAR JUMP. EQUATIONS DESCRIBING THE CHARACTERISTICS OF THE EXPANDING CHANNEL JUMP ARE DERIVED. THE OBSERVATIONS WERE CONDUCTED USING SIX DIFFERENT ANGLES OF DIVERGENCE. THE EXPERIMENTAL RESULTS SHOWED A CLOSE AGREEMENT WITH THE THEORETICAL SOLUTIONS. THE GENERAL EQUATION DEVELOPED FOR THE JUMP, WITH PROPER EVALUATION OF THE SIDE PRESSURE FORCE EFFECT, DESCRIBES THE PHENOMEN REGARDLESS OF THE ANGLE OF DIVERGENCE. AN EMPIRICAL EXPRESSION FOR APPROXIMATING THE LOCATION OF THE JUMP WITHIN THE TRANSITION WAS ALSO DEVELOPED. /AUTHOR/
