Computational Fluid Dynamics of a Semi Batch Reactor for Heavy Oil Hydroconversion

摘要

This work presents the numerical results of the computational fluid dynamics of a semi batch reactor used for hydroconversion of heavy oil. The reactor is a multicomponent system, and it is modeled as a pseudo two phase system (gas + slurry). The equations used are the continuity equations, the momentum equation (Navier-Stokes), and the k-e for turbulence. The numerical method used to solve the mathematical method was the finite volume, where the problem was divided in two domains, in order to account for the moving part of the impeller. The numerical results indicated convergence of the procedure for the velocity profiles.
