A 1/4-scale flow-model of the PM-1 vessel configuration was fabricated and tested to observe the flow distributions and pressure drops associated with this design. Flow distribution in the inlet water box was found to be independent of velocity and Reynolds number in the range tested. A pressure recovery from the kinetic energy of the inlet flow was observed. This caused a minimum flow from the water box at the inlet side of the vessel and a maximum flow at the opposite side. The flow variation resulting from the water box was reduced by the characteristics of the flow annulus formed by the thermal shields. The overall pressure drop measured from inlet to outlet was 23 ft of head as compared with the predicted value of 21 ft. (J.R.D.)Read More
