Once a simulation highlights critical stress zones vulnerable to hot cracking, engineers can test mitigation strategies directly within the software. Geometric Modifications
Flow-3D Hydro crack hot
Based on these risk maps, aerators were designed using a combination of ramps, offsets, grooves, and duct aerators. Four different aeration scenarios were evaluated, and the best configuration — incorporating four aerator systems — significantly improved cavitation damage mitigation: the cavitation number increased by approximately 70%, the maximum air concentration reached 0.868, and damage levels were successfully reclassified from major damage to no damage while maximum velocity decreased from 33 m/s to 19 m/s. flow 3d hydro crack hot
