The Thermal and Fluids Engineering Division research work is focused on modelling and analysis of products, machines and systems where fluids flows are involved, with or without thermal phenomena. This is done by means of modelling and simulation based on CFD (Computational Fluid Dynamics) techniques and by means of experimental tests. These is applied to develop new designs, improve ant optimize current designs and the development of user-oriented design and simulations tools.

Their research lines are the following:

  • Thermal and Fluid Processes and Machines. Mathematical modelling and simulation by using Computational Fluid Dynamics (CFD) of fluid flow and heat transfer in all types of industrial equipment: turbomachines, water meters, valves etc. Mathematical modelling in concentrated parameters. Experimental tests to obtain the operating parameters. Analysis and optimization of the design.

  • Multiphase Flows. Mathematical modelling, simulation, experimental analysis and optimization of: Atomization systems: sheet breaking and drop forming mechanisms. Melt-blown systems: high-speed airflow, formation and dynamics of polymer fibers. Wastewater treatment processes: Aeration of reactors and flotation systems by microbubbles (DAF).

  • Ventilation, Air Conditioning and Cooling. Mathematical modelling, simulation, experimental analysis and optimization of: ventilation processes and enclosure air conditioning by free and forced convection. Cooling of power transformation systems. Cooling of electronic components. Cooling of electrical machines.

  • Biofluid Dynamics. Mathematical modelling, simulation, experimental analysis and optimization in the field of Biofluids. Fluid-mechanical analysis of the arteries (abdominal aorta, hepatic artery...): experimental and numerical study of flow patterns and pressures. Research of the relationship between Fluid Mechanics and thrombus and aneurysms formation. Hepatic radioembolization: study of the influence of fluid-mechanical and geometric parameters on the targeting of liver tumors and catheter design.
