Abstract
The project is within the framework that the Research Group has developed in its general research line: "Mathematical formulation,
numerical resolution and experimental validation of fluid dynamics and heat and mass transfer phenomena", and particularly in the
numerical modelling of gas-liquid multiphase flows. In this context, an important motivation is to collect the Group's experience from
previous projects concerning basic and applied research, as well as consolidate and extend the work carried out in the development of
numerical methods for the Direct Numerical Simulation of free surface flows, interfacial flows, and dispersed multiphase flows. Therefore,
the aim of this project is to work deeply in the phenomenology of gas-liquid multiphase flows, with and without interfacial heat and mass
transfer, which are key in the understanding of both the fundamental physical and mathematical aspects, as well as in the knowledge of
thermal equipment and engineering systems in industrial, aerospace and chemical applications. For example: solar energy of high
temperature, industrial nuclear reactors, bubble columns, refrigeration systems (vapour compression and absorption cycles), cryogenic
flows, desalinization, combustion chambers (liquid fuels), gas turbine nucleation, etc. In addition to the scientific impact of the project
(participation in international conferences, scientific publications in the most relevant international journals, doctoral thesis, infrastructure
set-ups, the development of advanced numerical tools, etc.), the achievements of the project will be very important to expand the
comprehension of the fundamental aspects of the interfacial heat and mass transfer in multiphase flows. In the medium term, this project
will allow the improvement of thermal systems and equipment as the ones indicated above. The project, with a total duration of 3 years,
has been structured into three main areas: i) direct numerical simulation of gas-liquid multiphase flow with and without heat and mass
transfer applied to bubbles and droplets, ii) direct numerical simulation and experimental validation of falling-film flows, and iii) implementation of Euler-Lagrange methods for simulation of dispersed
multiphase flows. In the framework of these main research lines, three important technological applications will be developed: i)
condensers, evaporators and reactors used in different industrial fields, ii) absorption refrigeration and desalinization, and iii) spray
injectors and combustion chambers.
