Vacuum generation or cavitation is a process consisting of production, transfer along with fluid and collapse of bubbles as a result of interaction to the inner walls. The main goal in this study is to investigate the movement of produced microbubbles and estimate the interaction of bubbles on the inner wall of pipes with surface blockages with different percentages of blockages and pipes with elbows considering different inlet flow rates inside. The simulation results for clogged pipes show that the more clogged the pipe is, the higher the probability of microbubbles hitting the clogged area and bursting, which is why the possibility of damage to the pipe wall is increases. Furthermore, in the high percentage of blockages at the pipe (above 36%), the higher the flow rate of the fluid entering the pipe, the higher the probability of damage due to more microbubbles hitting the wall increases significantly. However, in the low clogging percentage of the pipe (less than 36%), the lower the velocity of the inlet fluid, the more likely the microbubbles will hit the clogging wall, and as a result, the more likely the pipes will be destroyed and damaged.
