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… More >
