Abstract:
The novelty of the proposed project is the extension of the finite-difference Lattice Boltzmann (FDLB) models developed for dilute gases to deal with both the dense gas flow and the liquid-vapor flow in curvilinear geometries. We plan to explore the dense gas behaviour in rarefied and confined setups, like the circular Couette flows (between two coaxial cylinders), the heat transfer between coaxial cylinders and concentric spheres, as well as liquid-vapor flows, like the spherical droplet evaporation or the bubble growth in a metastable liquid.
We plan to implement the simplified Enskog collision operator in the FDLB framework and validate the model against the direct evaluation of the Enskog equation obtained by using a particle method. We wish to apply the resulting models to unbounded (normal shock wave structure) and bounded (Couette and Poiseuille flows) dense gas problems, exploring the full range of the Knudsen number, as well as various values of the confinement ratio. Next, we want to add the Vlasov term (used to model intermolecular attraction) to the Enskog equation, in the framework of FDLB in order to model liquid-vapour flows (e.g. evaporation and condensation phenomena). The behaviour of dense gases and liquid-vapour systems in curvilinear geometries will be explored using the vielbein LB models, enhanced with the simplified Enskog collision operator and the Vlasov term.

Abstract:
The goal of the project is to improve the institutional performance of the partners, including those with the potential for relaunching, by developing space and security competencies and by encouraging the orientation of research activities in pragmatic directions. Space activity involves the development of technologies and technologies validated in extreme conditions, which have significant applicative potential in various priority economic and social domains.
The VESS project is based on the experience gained by the Coordinator through participation in ESA scientific missions, the development and validation of flight software and hardware components, the development of countermeasures in the context of human crew space missions. Partners contribute with their own skills in areas such as math physics, computer science, advanced technologies, astronomy. VESS will provide knowledge sharing and exploitation within and outside the consortium by creating technology transfer and knowledge transfer offers to other areas of activity. Furthermore, VESS will allow joint use of existing research infrastructures for partners. The four component projects are oriented, each by its specificity, both to the consolidation of the Romanian presence in the activities of ESA, as well as to the capitalization in the economic and social environment of the obtained results. Ensuring synergic interaction between component projects at the level of the complex project will maximize the chances of success and superior valorisation of the results. The joint RDI program to be developed will lay the foundations for a field of competence in space and derivative applications. The offer of services to the socio-economic environment will be achieved by organizing workshops that will be provided with adequate advertising. The patenting of the results will be done by the partners directly involved in the activities that produced these results.

Abstract:
The construction of lattice Boltzmann models for the simulation of relativistic gas flows is a relatively new research field. We propose to contribute to this field by reformulating the formalism of the Boltzmann equation and the method for the discretisation of the momentum space using the tetrad formalism, through which the mass-shell condition is decoupled from the space-time geometry. Furthermore, we propose the development of lattice Boltzmann models of arbitrary order using modern quadrature methods, valid for particles of arbitrary masses. Finally, we propose the application of the methodology described above to the study of gas flows in general relativity (flows on a gravitational wave background, scattering of gas on black hole space-times, thermal states on rotating space-times, etc).

Abstract:
The project is dedicated to the development and application of three-dimensional (3D) Lattice Boltzmann (LB) models for the study of complex fluids and their micro-scale behaviour. LB models allow the easy incorporation of interparticle forces as well as of boundary conditions and are appropriate for implementation on massively-parallel computers. Intensive simulations will be done on the IBM Blue Gene P system recently inaugurated at
the West University of Timisoara, as well as on a "desktop supercomputer" incorporating two Graphics Processing Units (GPU), to be set up at the host Institution. Simulations will be conducted in order to understand the effect of various conditions (fluid viscosity, temperature gradients and/or anisotropy induced by gravity or shear flow) on the phase separation process and the scaling exponents that characterize the domain growth in single- or multicomponent fluid systems. The morphology of the 3D structures formed during the phase separation, as well as their dynamics, will be investigated using the Minkowski functionals. Specific problems in microfluidics will be also investigated through 3D Lattice Boltzmann simulations: rarefaction effects in long microchannels, temperature dip in force-driven flow and thermal creep. The formation of drops or bubbles introduced in the co-flowing phase via a capillary tube or a T-junction will be another process to be analyzed through LB simulations in three dimensions.
