| Summary: | Oil is usually transported from oneplace to another in the form of suspension, which
is a mixture of water and oil. The suspension flows in the pipeline driven by pressure
drop between an inlet and an outlet. Knowing suspension arrival time at the outlet
is important for the efisien of pump activity. In this study, the head and tail position
of the suspension at any time will be calculated by taking into account pressure and
pipe geometric. The suspension flow models are governed by second order ordinary
differential equations and then solved by using finite difference method. In this
model there are two unknown parameters, friction force due to pumping equipment
and shear stress of turbulent flow, that should be estimated. Genetic algorithm is
used to estimate those parameters. |
