Erosion Analysis for the Misaligned U2 Nozzle and its Connector Block

Erosion Modeling Analysis For Modified DWPF SME Tank

“…In this case 30 o incident angle into the region of the coil guide was established by the previous study [2] since the sensitivity results show that the 30 o incident flow field creates an overall erosion pattern close to the one observed by the recent inspections. In addition, the literature data [2,3] The present analysis is mainly concerned with the erosion estimations for the tank floor. The results show that serious erosion damages can occur to the tank floor as well as the 0.25-in thick insert plate when the agitator impeller operates continuously at 130 rpm, even though the wall shear at the tank floor is reduced by about 30% compared to the original geometry results.…”

“…Detailed governing equations for the continuous phase were provided in the previous work [2,3]. Reynolds number for the flow condition is found to be in the range of about 10 5 , which corresponds to a fully turbulent regime.…”

“…Ductile material such as stainless steel is damaged by wall mechanism when particles impinge on the ductile surface of the present coil guide at attack angles near 30 o . Previous results [2,3] showed that the primary locations of high erosion due to particle impingement are at the occurrence of sudden change of flow direction, sudden contraction, and flow obstruction. Transport equations that govern slurry flow, and the erosion mechanism established by the previous work [2] were used to evaluate the high erosion sites and the primary cause of erosion damage created by the SME mixing .…”

“…In the previous work [2,3] a literature survey was performed to identify the principal mechanisms of wear for a solids laden fluid and to find out what other wear studies and experiments have been done.…”

Erosion Modeling Analysis For DWPF MFT/SME Tanks

“…In the previous work [2,3,4] Available evidence suggests that the key to understanding erosion in flow systems is a detailed knowledge of the coupled and complex phenomena of solids circulation and fluid motion. One problem arising from slurry flow is the wear it creates on the tank wall.…”
