INFLUENCE OF JET-TO-MAIN STREAM TURNING ANGLE IN FLUID FLOW FROM CYLINDRICAL NOZZLE OF COLLECTOR-PIPELINE ON FLOW COEFFICIENT

For intake cylindrical nozzles with orthogonal lateral jet outlets, dependences of the flow coefficient  on (1) Reynolds number , (2) jet-to-main stream turning angle , which is measured relative to the direction of the main stream in a collector-pipeline, as well as (3) the ratio  of the diameter of the outlet hole of the nozzle to that of the collector-pipeline are obtained. The ratio  influences the value of the coefficient of flow more considerably than the jet-to-main stream turning angle does. The magnitude of flow coefficient varies most abruptly in the range of the magnitude of the ratio  from 0.35 to 0.40. For adjustment of non-uniformity of the fluid inflow into the pressure pipelines along their lengths, the nozzles of 0.35 0.40 are the most suitable ones.
