Constructal theory of global circulation and climate [PDF]
, 2006 The constructal law states that every flow system evolves in time so that it develops the flow architecture that maximizes flow access under the constraints posed to the flow.

Leakage Evaluation by Virtual Entropy Generation (VEG) Method
Entropy, 2017 Leakage through microscale or nanoscale cracks is usually hard to observe, difficult to control, and causes significant economic loss. In the present research, the leakage in a pipe was evaluated by the virtual entropy generation (VEG) method. In virtual

Heat transfer and entropy generation optimization of forced convection in a porous-saturated duct of rectangular cross-section [PDF]
, 2007 We investigate analytically the first and the second law characteristics of fully developed forced convection inside a porous-saturated duct of rectangular cross-section. The Darcy-Brinkman flow model is employed.

Thermal Analysis in Pipe Flow: Influence of Variable Viscosity on Entropy Generation
Entropy, 2004 : Flow through pipes and heating situations find wide applications in industry. Depending on the fluid properties, temperature field in the pipe changes. This in turn results in thermodynamic irreversibility in the flow system.

Journal of Materials Research and Technology, 2023 The objective of this present study is to use entropy generation to predict the fatigue life behaviour of magnesium alloy. As the energy dissipation rate directly correlates with material degradation and increases in temperature, the entropy generation ...

Dissipation in intercluster plasma [PDF]
, 2007 We discuss dissipative processes in strongly gyrotropic, nearly collisionless plasma in clusters of galaxies (ICM). First, we point out that Braginsky theory, which assumes that collisions are more frequent that the system's dynamical time scale, is ...

Second Law Analysis of a Reactive MHD Couple Stress Fluid Through Porous Medium [PDF]
, 2017 In this work, effect of magnetic field on the entropy generation rate of a reactive couple stress fluid through porous medium is investigated. The equations governing the fluid flow are formulated, nondimensionalised and solved using the rapidly ...
