The Tribo-Dynamics Performance of the Lubricated Piston Skirt–Cylinder System Considering the Cylinder Liner Vibration
TL;DR: In this article , a multiphysics coupling method was proposed to model and analyze the lubricated piston skirt-cylinder interface considering the cylinder liner vibration, and the results indicated that increasing the stiffness and damping coefficient of the cylinder is beneficial to suppress the vibration of the system, but it has little effect on the tribological characteristics of the piston skirt.

Numerical modelling of ultrasonic waves in a bubbly Newtonian liquid using a high-order acoustic cavitation model.
TL;DR: A non-linear acoustic model is validated against reference water pressure measurements from acoustic waves produced by an immersed horn and predicts that the most intense cavitation activity is localised below the vibrating horn and estimates the acoustic decay below the sonotrode with reasonable qualitative agreement with experimental data.
