- During his
studies in the Department of Mechanical Engineering at the
Universidad Pontificia Bolivariana in Medellin-Colombia, Juan
Hernandez became interested in research, when in 1996 Professor
Farid Chejne invited him to be part of the Energy and Thermodynamics
Institute (IET). Here, Juan Hernandez focused his studies in
numerical simulation, transport phenomena and irreversible thermodynamics.
- From 1996 to 2000 at the IET, he participated in several research projects in the area of numerical simulation, such as: coal gasification and combustion processes, cooling towers and desiccant dehumidification cooling processes; using finite element, finite volume and finite differences techniques.
- In 1997, the IET created a group called the Advanced Numerical Techniques Area, due to the growing interest of using boundary integral equations for non linear flows (high Reynolds numbers and non Newtonian fluids). In principle this area was focused in the development of new techniques to approximate the non linear terms in the general momentum equations, in order to be solved by the Boundary Integral Method. As part of this area, his ME degree project was: "Dual Reciprocity and Boundary Elements for Newtonian and non-Newtonian Fluid in Three Dimensions".
- The research project found that Dual Reciprocity was not enough in order to approximate the non linear terms in the momentum equations. In fall 2000, Juan Hernandez started a Ph.D. program at the Mechanical Engineering Department under the advisorship of Professor Osswald (a pioneer of Boundary Integral Methods for non-Newtonian fluids). The purpose of the research project is to continue the development of approximation techniques for boundary integral equations to simulate polymeric flows including free surfaces and solids in suspension.
- Additionally, Juan Hernandez participates in projects of fiber damage mechanisms, curing kinetics and visco-elasticity models.
