According to hydrodynamic theory, based on CFD software-Fluent, the simulation for Newtonian fluid flow in helical coiled tubing was carried out to reveal the flow characteristics and pressure gradient of the helical section. Laminar and turbulent flow with different inlet velocities are considered. The results are compared with other published correlations. The results show that maximum velocity distributes in the outer side of the coiled tubing. The velocity in turbulent flow is more uniform than in laminar flow. It is shown that the faster the inlet velocity, the greater the pressure gradient increment. CFD simulation is in close agreement with the published correlations.
