Abstract

This thesis explains the simulation of bubbles rise in cavity using Lattice Boltzmann Method. The two phase bubbles simulated using Lattice Boltzmann Equation. The simulation was done on two dimensional only and multiple bubbles motion under buoyancy was carried out. Three configurations of the bubble simulation was being simulated using LBM code development. Free energy model was reviewed and the base on isotropy approach (Yonetsu Approach) used and Galilean invariance are also considered. Three variations of configuration used which are distance between bubbles, configuration base on differential of Eotvos number, and configuration base on different Kappa number. The result obtained from simulation is proven by lattice Boltzmann method which to be used for multiphase. Simulation results are validated and has good agreement with previous studies. The experimental setup for bubble rise was fabricated and due to some limitations, results obtained are not well satisfied.
