Experimental Study of Flow Hydrodynamics Lead Coolant and Water through the Experimental Section «Throttle Clearance-Ring»


Issue of journal:


A research and comparison of the hydraulic characteristics of the water and lead coolant (T = 400–500°С) flow in the system of local hydraulic resistances «throttleannular gap» have been done at the Alekseev Nizhny Novgorod State Technical University. During the experiments the magnitude
of the relative clearance (2∆/d = 0,018; 0,036; 0,056) was varied with the static and rotated shaft. The average speed inside the annular gap ranged between 0,01 and 0,1 m/sec, the coolant was saturated with the oxygen.
