DETERMINATION OF TRANSITION ZONES IN SETTLING BASINS

A VISUAL METHOD FOR DETERMINING THE FLOW FIELD WHICH EXISTS IN A SETTLING BASIN WAS DEVELOPED. THE METHOD INVOLVES PHOTOGRAPHING THE PATH OF PARTICLES WHICH BEHAVED AS THE FLUID TO DETERMINE COORDINATE POSITIONS THAT COULD BE DETERMINED AS A FUNCTION OF TIME. THE DEVELOPED METHOD CAN QUALITATIVELY EVALUATE THE FLOW FIELDS AND OUTLETS FOR SETTLING BASINS. THE DISTANCE IN THE DIRECTION OF FLOW REQUIRED FOR THE INLET JET ACTION OVER A SHARP EDGED WEIR TO BECOME DISPERSED INCREASES AS THE HEIGHT OF THE WEIR DECREASES, AND THE EFFECT IS EXTENDED FURTHER DOWNSTREAM IF THE FLOW RATE IS INCREASED FOR A GIVEN WEIR HEIGHT. NAPPE CURVES OVER SHARP EDGED INLET WEIRS WERE OBTAINED FOR A RELATIVELY DEEP SETTLING BASIN MODEL AS A RESULT OF THE DEVELOPED FLOW VISUALIZATION METHOD.
