Abstract
The results of fluid flow simulation in a double L-bend pipe with small nozzle
outlets are presented in this paper. The pipe geometry represents a sparger for a
mixing process in a tank. The flow simulation was performed with a
commercially available computational fluid dynamics package, Star-CD. The
effects of the L-bend and small nozzle outlets on the velocity and pressure
distributions in the pipe are discussed. The discussion will lead to an improved
design of the sparger with the objective of obtaining a uniform fluid discharge
from the nozzle outlets.
Keywords: flow simulation, computational fluid dynamics, velocity and pressure
distributions.
1 Introduction
The primary process in manufacturing computer hard discs is the process of
coating nickel sulphamate solution onto the discs. The nickel solution is
normally fed into a mixing tank via a double L-bend pipe, which represents a
sparger with small nozzle outlets. However, the coating process may be affected
by non-uniform distribution of the nickel solution inside the mixing tank,
resulting in an uneven nickel coating thickness at the discs surface. It is therefore
desirable to have a uniform fluid discharge from the pipe nozzle outlets in order
to obtain a uniform distribution of the nickel solution inside the mixing tank. The
variables that may be changed in order to get the optimum results would be the
pipe geometry, design or even the control of pressure of the fluid flow as
