The group of Iermal and Fluid Engineering focuses on the modeling and analysis of systems, processes and products involving fluid flows (with or without thermal phenomena). To this end, CFD (Computational Fluid Dynamics) modeling and experimental techniques are used to develop new designs, improve and optimize current ones and develop simulation, design and analysis tools oriented to Username.

Its lines of research are as follows:

 Thermal and Fluid Machines and Processes. Mathematical modeling and simulation by Computational Fluid Dynamics (CFD) of flow and heat transfer in all subject of industrial equipment: turbomachines, water meters, valves, etc. Mathematical modeling in concentrated parameters. Experimental obtaining of operating parameters. Analysis and optimization of design.

Multiphase flows. Mathematical modeling, simulation, experimental analysis and optimization of: Atomization systems: mechanisms of sheet breakage and training of droplets. Melt-blown systems: high velocity air flow, training and dynamics of polymer fibers. Wastewater treatment processes: Reactor aeration and flotation systems using microbubbles (DAF).

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

Biofluidics. Mathematical modeling, simulation, experimental analysis and optimization in the field of Biofluidics. Fluid-mechanical analysis in arteries (abdominal aorta, hepatic artery...): experimental and numerical study of flow patterns and pressures. research of the relationship between Fluid Mechanics and training of thrombus and aneurysms. Hepatic radioembolization: study of the influence of fluid-mechanical and geometrical parameters in the targeting of hepatic tumors and design of catheters.
