ABSTRACT = {Avoiding cavitation inside the water jacket is one of the most important issues regarding the proper design of a 
diesel engine’s cylinder liner. Using CFD simulations conducted in the frame of a mixture multiphase approach, a 
moving grid technology and near-wall cavitation model, in the present study the factors and fluid-dynamic patterns that influence cavitation are investigated from both macroscopic and mesoscopic perspectives. Several factors are examined, namely: wall vibration, water jacket width, initial cavitation bubble radius, coolant 
temperature, and number of bubbles. The results show that reducing the cylinder liner vibration intensity can 
significantly weaken the cavitation. Similarly, increasing the water jacket width is instrumental in avoiding 
cavitation. Increasing the coolant temperature reduces the microjet velocity related to bubble collapse, while 
increasing the number of bubbles produces a much larger water hammer pressure that can cause more damage to 
the cylinder liner.},
