Entropy generation rate during laser pulse heating: Effect of laser pulse parameters on entropy generation rate

Optics and Lasers in Engineering, 2008
Laser pulse heating of solid surface and entropy generation during the heating process are considered. Time exponentially decaying pulse is accommodated in the analysis and the laser pulse parameter (β1/β2) resulting in minimum entropy generation rate is computed. Analytical solutions for temperature rise are presented and volumetric entropy generation

Determination of LEDs degradation with entropy generation rate

Journal of Applied Physics, 2017
We propose a method to assess the degradation and aging of light emitting diodes (LEDs) based on irreversible entropy generation rate. We degraded several LEDs and monitored their entropy generation rate (Ṡ) in accelerated tests. We compared the thermoelectrical results with the optical light emission evolution during degradation.

Flow-Induced Endothelial Surface Reorganization and Minimization of Entropy Generation Rate

Journal of Biomechanical Engineering, 2004
Effects of hydrodynamic shear on the shape of the endothelial surface are examined based on evaluations of the rate of entropy generation at the cell surface. A linear solution of the flow over a sinusoidally varying endothelial surface is used to evaluate the entropy generation rate on the cell surface for which measured cell dimensions are available.
