Entropy flow and energy efficiency analysis of extractive distillation processes with a heavy entrainer [PDF]
, 2014 International audienceThe minimization of the entropy production is equivalent to minimizing the work or energy consumption required by a separation process. Sources of entropy creation during the extractive distillation of a minimum- and maximum boiling

Entrainment Concepts Revisited
Journal of Biological Rhythms, 2010 The traditional approaches to predict entrainment of circadian clocks by light are based on 2 concepts that were never successfully unified: the non-parametric approach assumes that entrainment occurs via discrete daily phase shifts while the parametric approach assumes that entrainment involves changes of the clock’s velocity. Here the authors suggest

Complexity Analysis of Bubble Plumes in Power Law Fluids Based on Chaos Theory
Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT In order to reveal the complexity of the internal flow of bubble plume in power law fluid, the flow characteristics and chaotic characteristics of plume are studied by experiment and theory. The chaotic characteristic parameters (correlation dimension D, K entropy, and Lyapunov exponent λ) of gas velocity under different superficial gas ...
