Prof. Rafael Gabler Gontijo is an Associate Professor of Fluid Mechanics at the University of Brasilia - Brazil. He is a Mechanical Engineer with a Masters in Science and PhD degree in Fluid Mechanics by the University of Brasilia. He also made a specialization course in Equipment Engineering by Petrobras Coorporative University.
Professor Gontijo has a great experience in scientific programming in Fortran language. He has published several articles in International Conferences in the field of numerical simulation of complex turbulent flows with forced and natural heat convection. At this stage of his research he used the Finite Element Method and RANS methodology to explore the efficiency of high Reynolds turbulence models with sophisticated wall functions to model the effects of adverse pressure gradients inside turbulent boundary layers.
The focus of his actual research is the Hydrodynamics of Magnetic Fluids. This study has two important approaches: the microstructural behavior of magnetic suspensions and the macroscopic model of non linear PDE's that rules the motion of non symmetric polar fluids in the presence of external magnetic fields. This topic of research started to be investigated by Professor Gontijo during his PhD and resulted in the publication of several scientific papers published in indexed Journals. His PhD Thesis won the Prize of the Brazilian Society of Mechanical Sciences as the best Thesis in the Field of Mechanical Sciences in the years of 2013-2014.
Professor Gontijo is also a reviewer in the field of Fluid Mechanics of the Journal of the Brazilian Society of Mechanical Sciences and Engineering. He has lectured the following disciplines: Boundary Layer Theory, Transport Phenomena, Fluid Mechanics and Hydrodynamics of Magnetic Fluids. He is also the coordinator of the Fluid Mechanics Laboratory at the University of Brasilia and the second leader of the Vortex Group, together with Prof. Francisco Ricardo Cunha, who coordinates the Microhydrodynamics Lab at the same University.
Just recently Prof. Gontijo has published some papers in international journals of high impact factor in the classification of Capes (Brazilian regulatory agency of research), such as the Journal of Magnetism and Magnetic Materials (JMMM), Journal of Nanoscience and Nanotechnology (JNN) and Powder Technology.
The main goal of Professor Gontijo research is to study, learn and understand the physical laws that govern the behavior of fluid systems and if possible contribute through his skills for the production of high quality science in the field.
