Nelson Gonçalves graduated in Mathematics Teaching from Universidade de Aveiro in 2005, obtained the Master’s degree in Mathematical Engineering from Faculdade de Ciências da Universidade do Porto in 2007 and obtained the PhD on Science and Engineering of Polymers and Composites from Universidade do Minho in 2014, whose thesis title is “Computer Aided Design of Extrusion Forming Tools for Complex Geometry Profiles". From September 2004 to August 2007 he was Mathematics Teacher in several schools. On November 2006 he started his master thesis about Finite Volume Method on Unstructured Meshes, applied to cooling problems that occur on extrusion process. After the master thesis he develop the research in the profiles cooling process on the stationary and uniform velocity problems. During the PhD, he developed a numerical rheological code able to predict the flow on extrusion dies that was used to aid the design of extrusion dies and the cooling systems of the extrusions process. Since February 2014 he’s a post-doctoral fellow at LSRE, where he studies the mixing mechanisms in Confined Impinging Jets Reactors through numerical simulation. The influence of pulsation of the jets on mixing and the turbulent kinetic energy dissipation are the main issues of his current research.
