چکیده

Thermodynamics is defined as the science of energy and entropy which are applicable to all fields of science and engineering. This special issue is essentially devoted to the entropy generation in thermal engineering systems and applications. Entropy generation is one of the most significant problems to overcome to optimize a system/process and its performance, and this will unfortunately remain as a crucial problem to the next generation. In this regard, better understanding of the concept of entropy and its role amo ng various classes of thermal systems and processes with a diverse coverage is crucial. Research into transport phenomena in energy systems and applications has substantially increased during the past a few decades due to its diversity in applications. This makes the special issue a most timely addition to existing literature. It includes recent major developments in both the fundamental and applications, and provides a valuable source to researchers dealing with analysis of entropy generation in thermal systems and processes. This special issue contains 14 technical papers on entropy generation in thermal systems and processes ranging from heat engines to natural/forced convection systems. The collection of topic included is suitable for a wide range of interests from practitioners to researchers working on thermal systems and processes. Each paper was peer-reviewed under the guidelines of the Journal before publication.

Investigation of the Slipping Wear based on the Rate of Entropy Generation

Wear is a complicated phenomenon caused by the relative movement of two contacting surfaces compressed together by a normal force. Prediction of the wear, in most cases, requires various experiments and microstructural characterization of the contacting surfaces. Mathematical models based on physical concepts could provide considerable help in understanding the physical behavior and hence the p...

Entropy generation in hydromagnetic and thermal boundary layer flow due to radial stretching sheet with Newtonian heating

The entropy generation during hydromagnetic boundary layer flow of a viscous incompressible electrically conducting fluid due to radial stretching sheet with Newtonian heating in the presence of a transverse magnetic field and the thermal radiation has been analyzed. The governing equations are then solved numerically by using the fourth order Runge-Kutta method with shooting technique. The eff...

Influence of inclined Lorentz forces on entropy generation analysis for viscoelastic fluid over a stretching sheet with nonlinear thermal radiation and heat source/sink

In the present study, an analytical investigation on the entropy generation examination for viscoelastic fluid flow involving inclined magnetic field and non-linear thermal radiation aspects with the heat source and sink over a stretching sheet has been done. The boundary layer governing partial differential equations were converted in terms of appropriate similarity transformations to non-line...
