Optimal hydraulic design of an ultra-low specific speed centrifugal pump based on the local entropy production theory

Proceedings of the Institution of mechanical engineers. Part A, journal of power and energy, 2019
The ultra-low specific speed centrifugal pump has been widely applied in aerospace engineering, metallurgy, and other industrial fields. However, its hydraulic design lacks specialized theory and method.

General theory for localizing the where and when of entropy production meets single-molecule experiments

Proceedings of the National Academy of Sciences of the United States of America
Significance The operation and manipulation of complex systems on the nanoscale usually takes place out of equilibrium. In experiments like force spectroscopy, one observes the system under time-dependent external driving, but typically such observations

On extremal entropy production in the solid-body conductance theory

Doklady Physics, 2001
It is shown that, in one-dimensional geometry, the principle of the minimum of entropy production in equilibrium final states is correct in one general situation. Two examples taken from the solid-body conductance theory are considered. For a solid body with no external loads and no regard for heat expansion, which ensures the constancy of stresses and
