Facultad de Informática Universidad Complutense de Madrid SimBoltz: simulación de fluidos mediante el método Lattice Boltzmann Página 3 de 54 Resumen El método Lattice Boltzmann permite resolver problemas de mecánica computacional de fluidos, en los cuales se simula el comportamiento de un flujo con ciertas características. Para aplicar las ecuaciones del método, debe discretizarse el espacio estudiado en cierto número de celdas por cada dimensión. En el presente desarrollo, se ha aplicado el modelo D2Q9 para 2 dimensiones en varios escenarios, unos correspondientes a problemas típicos de mecánica de fluidos y otros de propia creación, obteniendo comportamientos del flujo muy próximos a la realidad. Abstract Lattice Boltzmann Method solves problems of computational fluid dynamics, in which simulates the behaviour of a stream with certain characteristics. To apply the equations of the method, the studied space must be discretized in a number of cells for each dimension. In this development, D2Q9 model for two dimensions has been applied in various scenarios, some of them typical problems related to fluid mechanics and others of own creation, obtaining flow behaviours which are very close to reality. Palabras clave Método Lattice Boltzmann, simulación fluido incompresible, vórtice, corriente, cavidad lid-driven, Karman, bounce-back, condición periódica frontera, OpenGL.

What students are saying

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
