Special Issue Information

Dear Colleagues,

The importance of the study of turbulent flows is well known, as they are typical in industrial applications. There are many studies in the literature dealing with the analysis of turbulent flows for different configurations, on the other hand many aspects need further investigation.

The focus of this special issue is on the study of the entropy generation in turbulent flows from the theoretical or applicative point of views.

Entropy generation can be used as a practical framework for design and optimization of devices characterized by turbulent flows, in order to improve their efficiency, as in the case of combustion chambers, vortex tubes, turbulence promoters and porous media. This could be an area worth of investigation, in order to promote the utilization of entropy generation analysis in the engineering practice.

Furthermore, theoretical investigation is necessary to provide simple approaches for the estimation of entropy generation in numerical models, for example when turbulence models other than k-ɛ are taken into account.

These are only two examples of areas worth investigations and the present special issue is open to consider high quality papers dealing with other aspects of entropy production in turbulent flows.

The long-wave approximation of a falling film down an inclined plane with constant temperature is used to investigate the volumetric averaged entropy production. The velocity and temperature fields are numerically computed by the evolution equation at the deformable free interface. The dynamics of a falling film have an important role in the entropy production. When the layer shows an unstable evolution, the entropy production by fluid friction is much larger than that of the film with a stable flat interface. As the heat transfers actively from the free surface to the ambient air, the temperature gradient inside flowing films becomes large and the entropy generation by heat transfer increases. The contribution of fluid friction on the volumetric averaged entropy production is larger than that of heat transfer at moderate and high viscous dissipation parameters. Full article
