Abstract

Močljivost je lastnost materialov, ki igra v vsakodnevni in industrijski uporabi veliko vlogo. Načrtovanje novih materialov je ponavadi dolg in težaven postopek, ki v praksi mnogokrat zahteva tudi izdelavo večjega števila prototipov. V magistrskem delu so predstavljeni koncepti in implementacija testiranja močljivosti površinske topologije materialov s pomočjo računalniške simulacije tokov. Za proces simuliranja tokov smo uporabili mrežno Boltzmannovo metodo in jo optimizirali za izvajanje na GPE. Sistem smo ovrednotili s Poiseuillovim tokom in testirali na površinah, generiranih na podlagi postopkovnih šumnih funkcij. Močljivost smo nato ocenili z lastnim algoritmom na pridobljenih volumetričnih podatkih simulacij in pokazali odvisnost med nekaterimi postopkovno generiranimi površinami in kontaktnim kotom.

Secondary title: Wettability simulation of surfaces using the lattice Boltzmann method
Secondary abstract: Wettability is a property of materials that plays a major role in everyday and industrial use. However, designing new materials is usually a long and tedious process, which in practice often requires the production of a large number of prototypes. This master thesis presents concepts and implementation of testing the wettability of the surface topology of materials by means of computer simulation of flows. For the flow simulation process, we used the lattice Boltzmann method and optimised it for the GPU. The system was evaluated with Poiseuille flow and tested on surfaces generated by procedural noise functions. We then assessed the wettability using our own algorithm on the volumetric data obtained from the simulations and exposed the correlation between some of the procedurally generated surfaces and the contact angle.
