RESEARCH THESIS

Numerical Evaluation of Vertical Tanks Gas-Liquid Separation by

Gravity

This experimental theoretical research will address the

study of multiphase flows, specifically vertical separation

tanks, two phases, by gravity. The design of these devices is

governed by models based on empirical correlations. The study

was conducted in three phase: theoretical, experimental and

finally the comparison. The first comprehensive review, covers

the multiphase models and the proper selection of the

numerical model based on the conditions and requirements

analysis, the second is to perform computational experiments

and using of statistical models to determine the influence of

selected operating parameters to the final results and finally, comparing the obtained results of the computational model

with the different sources, such as the international standard

for the design of gravity separation tanks, ANSI / API 12 J

last edition and other sources. A program of Computational

Fluid Dynamics (CFD) will be used, so as to develop the

computational model to assess the conditions and parameters of

importance in the gravity separation tanks. The flow is

biphasic and fixed boundary conditions and initial parameters

will be defined. The simulation will be steady-state and gas

properties are considered constant. This study will make

recommendations to the purpose of improving the design of

vertical tanks by gravity separation of two phases. This

research will be presented on the international multiphase

fluid flow conference on July 2013 in Coru a, Spain.

UNDERGRADUATE THESIS

Modification to the PRODIC software to solve turbulent flows

under the presence of an internal wall condition

The main goal of this research was to develop a program to

solve and simulate turbulent flows in a quite realistic way.

The model k -[pic] is a semi-empirical model based on model

transport equations for the turbulence kinetic energy (k) and

its dissipation rate ([pic]). Like any model is no more than

an approximation. PRODIC grasped all the technical capability

of a commercial package. The main different is, that this kind

of software are open, therefore the user has to introduce all

the information through subroutines. This is done in order to

teach and show how simulators work. Computational Fluid

Dynamics (CFD) is based on the solution of differential

equations, these equation, are solved through numerical

methods and algorithms. The program worked with the Finite

Volume Method.
