Summary:
In support of an erosion evaluation for the misaligned mating surfaces of the U2 nozzle and its connector block in the 3H evaporator lift-separator jumper, the Engineering Modeling and Simulation Group (EMSG) has developed computational models to identify potential sites of high erosion. Two mechanisms were considered to evaluate high erosion locations representative of the actual flow process in the misaligned U2 nozzle, abrasive erosion which occurs by high wall shear of viscous liquid film, and chip-off erosion which is mainly governed by particle impingement. The results show that primary locations of the highest erosion due to particle impingement are at the occurrence of sudden change of flow direction, sudden contraction, and flow obstruction as expected. Potential damage sites due to the abrasive wall erosion are at the upstream and downstream regions of sudden changes of flow direction.
