Special Issue Information

Dear Colleagues,

Nowadays, computational fluid dynamics (CFD) has taken on great relevance in the study, design, and optimization of equipment, due to its great ability to simulate and model transport phenomena. CFD helps us to understand the multi-physical phenomena that occur in different kinds of devices, such as fuel cells, turbines and solar collectors, among others. Due to its reliability, several studies have demonstrated the use of CFD as a tool to improve industrial equipment and it is even used in the field of science, such as in medicine to predict diseases. In other words, CFD is used to create virtual environments to help us improve our understanding of the real world.

This Special Issue will accept unpublished original papers focused on the analysis of irreversibility by computational fluid dynamics on the following research areas:

  • Thermal equipment, such as fuel cells, solar collectors, heat exchangers, combustors, ovens, refrigeration cabins, etc.;
  • Devices used to generate energy, such as horizontal/vertical wind turbines, gas/vapor turbines, etc.;
  • Other equipment, such as compressors, blowers, stirred tanks, etc.;
  • Biological tissues, such as aorta, veins, heart, etc.;
  • CFD combined with optimization methods and entropy.

In this work, a numerical analysis of three different flat plate solar collectors was conducted using their entropy generation rates. Specifically, the Computational Fluid Dynamics (CFD) technique was used to compare the detailed performance of conventional and zigzag tube geometries of flat plate solar collectors (FPCs) in terms of their entropy generation rates. The effects of fluid viscosity, heat transfer, and heat loss of the flat plate solar collectors were considered for the local and global entropy generation rate analyses. Variations on the inlet volumetric flow rate of the FPCs from 1.0 to 9.0 L/min were simulated under the average solar radiation for one year in the state of Guanajuato, Mexico. The results illustrate and discuss the temperatures, pressures, and global entropy generation rates for volumetric flow variations. The velocity, temperature, and pressure distributions and the maps of the local entropy generation rates inside the collectors are presented and analyzed for the case with a flow rate of 3.0 L/min. These results demonstrate that the zigzag geometries achieved higher outlet temperatures and greater entropy generation rates than the conventional geometry for all the volumetric flow rates considered.
