Journal of Fluid Science and Technology, 2019 Much attention has recently been given to high-efficiency cooling of pistons in internal combustion engines by cooling channels because of improved thermal efficiency. Cooling a piston efficiently requires a grasp of the gas-liquid multiphase flow state.

Cooling Effects of “Cocktail Shaker” System on Pistons
JOURNAL OF THE MARINE ENGINEERING SOCIETY IN JAPAN, 1974 Although the cocktail shaker cooling of the piston has commonly been applied in high powered diesel engines, the evaluating method of the convective heat transfer rate between the piston surface and the cooling medium has not satisfactorily been made clear.

Thermodynamics of quantum systems under dynamical control
, 2015 In this review the debated rapport between thermodynamics and quantum mechanics is addressed in the framework of the theory of periodically-driven/controlled quantum-thermodynamic machines. The basic model studied here is that of a two-level system (TLS),

Influence of Test Temperature and Test Frequency on Fatigue Life of Aluminum Alloy EN AW‐2618A
Advanced Engineering Materials, EarlyView.The influence of test temperature and test frequency on the fatigue life of EN AW‐2618A is investigated. High‐cycle fatigue tests are performed at different test temperatures and frequencies on the 1000 h/230°C overaged state. Both test parameters reduce fatigue life due to time‐dependent damage mechanisms.

Dissipative collapse of the adiabatic piston [PDF]
, 2005 An adiabatic piston, separating two granular gases prepared in the same macroscopic state, is found to eventually collapse to one of the sides. This new instability is explained by a simple macroscopic theory which is furthermore in qualitative agreement
