This paper draws attention to an emerging body of work that relies on global thermodynamic optimization in the pursuit of flow system architecture. Exergy analysis establishes the theoretical performance limit. Thermodynamic optimization (or entropy generation minimization) brings the design as closely as ...

Pressure-volume (P-V) loop-based analysis facilitates thermodynamic assessment of left ventricular function in terms of work and energy. Typically these quantities are calculated for a cardiac cycle using the entire P-V loop, although thermodynamic analysis may be applied to a selected phase of the...
Effect of the Number of Injectors on the Mixing Process in a Rapidly Mixed Type Tubular Flame Burner Three-dimensional simulations are performed to study the non-reactive mixing process in a rapidly mixed type tubular flame burner (RTFB). The current work examines the effect of the number of ...

However, according to previous work on local entropy generation theory, the entropy generation caused by the turbulent fluctuating velocity is closely related to the turbulence model ε or ω used in the numerical calculation. Therefore, in the SST k–ω turbulence model, the entropy production ...
Work on the movement of liquids with stretching cylinders has attracted the attention of many researchers. It should be noted that the flow of the boundary layer due to surface shrinkage or stretching is a related type of flow that is reflected in several engineering and industrial processes. The...
