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
