“…The working fluid in the turbines undergoes high velocities, however, changes in kinetic energy do not generate a great impact compared to the enthalpy change, although VolControl allows the user the option of adding kinetic energy changes if desired. The energy balance for a turbine is shown in (6).…”

“…There are currently a variety of commercial software capable of simulating processes and equipment in order to achieve greater efficiency such as Aspen, ChemCAD, CCTherm, Pro / II, Simsci,etc. [6]- [10], however these have been developed for industrial purposes and cover so many topics that due to their robustness, lack of tutorials that facilitate the student learning. For this reason some software have been developed for educational purposes such as COMSOL Multiphysics, ANSYS Fluent, OpenCalphad, etc., having a great positive impact with their implementation in the teaching of thermodynamics [11]- [13], however these software have a high level of complexity, directing their use mainly on postgraduate students.…”

This paper presents the methodology and results of a parametric study to determine the influence of changing input variables on the behavior of a compressor and a turbine using a GUI registered in Matlab® called VolControl, and validated by the undergraduate students in mechanical engineering of the Universidad del Atlantico, which allows to perform the energy analysis of different stationary flow devices in a practical, interactive and user friendly way. The fundamental thermodynamic equations used for the development of the algorithm and the maximum error percentages obtained during the validation are presented. With the help of the software it was possible to determine the working fluid which cause the compressor to have a more optimum performance, as well as the quality level at the output of the turbine generating a high power output.

A rotating packed bed (RPB) is one of the cutting‐edge process intensification technologies due to its high mass transfer and mixing efficiency. Nevertheless, owing to the complex structure and hydrodynamic characteristics of RPBs, valuable data inside the reactor is hard to obtain by conventional experimental methods. Computational fluid dynamics (CFD) owing to its unique advantages of low cost, completeness of data and ability to simulate real and ideal conditions, has been adopted by many researchers to carry out fundamental research and practical application of RPBs in recent years. This paper therefore elaborates on the research progress on CFD simulation of RPBs. The building of a physical model of these reactors as well as selection of mathematical models are described, then applicability and accuracy of these models are compared and discussed. Simulation results for gas and multiphase flow in reactors are also presented. Additionally, the application of CFD to mixing and mass transfer between phases and processes in rotating packed beds is introduced. Optimum designs of reactors by the CFD method are also described. Finally, problems remaining with CFD simulation of rotating packed beds and future development directions are discussed. © 2018 Society of Chemical Industry

This paper presents the development of two cases of the first law of thermodynamics in open systems through the use of a registered graphical user interface (GUI) made in Matlab, as a complementary tool in the process of teaching undergraduate students of mechanical engineering from Universidad del Atlántico. Several experimental correlations reported in the literature for solving problems were considered. It was used the thermodynamic equations in the development of the algorithm of the software to perform energy analysis in a practical, interactive and user-friendly way, allowing students to identify the general behavior in nuzzles and heat exchangers when they operate under specific conditions. It was obtained the exit velocity profiles as a function of changes in temperature and pressure in nuzzles. In heat exchanges, the total heat transferred and the difference in temperature for the cold fluid is linearly dependent on the difference in temperature of the hot fluid with a higher efficiency when water is the cold fluid.
