Non-equilibrium dynamics of the piston in the Szilard engine
, 2018 We consider a Szilard engine in one dimension, consisting of a single particle of mass $m$, moving between a piston of mass $M$, and a heat reservoir at temperature $T$. In addition to an external force, the piston experiences repeated elastic collisions

Noise Reduction of an Axial Piston Pump by Valve Plate Optimization
Chinese Journal of Mechanical Engineering, 2018 Current researches mainly focus on the investigations of the valve plate utilizing pressure relief grooves. However, air-release and cavitation can occur near the grooves. The valve plate utilizing damping holes show excellent performance in avoiding air-
