My name is Ariel Gonzalo Hernández Sepúlveda and I currently work as a teacher and researcher at the Universidad Católica de la Santísima Concepción, Chile. I completed my studies in Civil Engineering in Chemistry in 2016 at the Universidad de Concepción, Chile. I completed my master's degree in Engineering Sciences with mention in Chemical Engineering in 2017 at the Universidad de Concepción, Chile. I also completed my PhD in Modeling and Experimentation in Science and Technology in 2024, at the Universidad de Extremadura, Spain. I have worked as a teacher and researcher in Engineering Sciences courses (Thermodynamics, Chemical and Thermal Processes, Thermodynamics and Fluids) since 2016. In addition, I have taught master's courses. All courses have been taught at the Universidad Católica de la Santísima Concepción, Chile. My research area focuses on the use of theoretical models such as simple equations of state (EoSs), cubic and advanced  (PC-SAFT and others) for the study of properties of pure fluids and their multicomponent mixtures of industrial interest, such as density, derived properties (molar excess volume, viscosity deviation), and phase equilibrium properties. On the other hand, the equations of state have been coupled with other models in order to obtain properties such as viscosity and interfacial behavior properties (surface tension, adsorption and desorption of the components in the mixture, interfacial thickness).
