Thermal Science

Research line: Fluid Engineering

This research line encompasses experimental and computational  simulation activities aimed at studying fundamental and applied problems involving fluid flow. Numerical simulations cover a a wide range of flows using finite volume and finite element techniques, including applications from low Reynolds number flows with free surfaces to turbulent flows at high Reynolds numbers and  multiphase flows. The development of turbulence models and efficient and robust computational methods is also one of the main focuses of this research line.. Another  area of research is the study of the rheological behavior of materials, considering their theoretical, numerical, and experimental  aspects and analyzing unconventional materials, such as viscoplastic and viscoelastic fluids.  Additionally, experimental and numerical research is  conducted in atmospheric pollution, involving the dispersion of particulate (aerosol) and gaseous pollutants. Advanced techniques for fluid  flow measurement, such as hot-wire velocimetry, laser-Doppler, and optical techniques using digital image processing of flows, are also developed and applied.

Research line: Thermal Machines
This research line focuses on developing simulation models and conducting experimental tests of heating,  cooling, air conditioning systems, and components. Emphasis  is placed on studying new refrigerants, non-azeotropic mixtures, hydrocarbons and air, as well as  developing high-performance heat exchangers. Applied thermal accumulation  in refrigeration or heating systems is also an investigated, focusing on phase change systems  such as encapsulated materials or ice slurry.  The Vehicle Engineering Laboratory (LEV) conducts studies related to fuel evaluation and engine performance.
Research line: Heat and Mass Transfer
 This research line involves theoretical, numerical, and experimental studies  addressing fundamental and applied aspects of heat and mass transfer problems. Numerical studies on combustion models and their industrial  applications are also addressed. These studies are complemented by advanced laser combustion diagnostic techniques.
