Due to the low temperatures of subsea water and the presence of waxes in the crude-oil, wax deposition might occur inside pipelines; causing transport problems; leading to economic problems for the petroleum industry and possible environmental disasters in the sea.One of the leading premises in most of the current wax deposition models is to only consider the axial component of the velocity in conservation equations.The wax deposition is a process proved to be driven by radial mass transport; therefore, these assumptions are presumed to reduce accuracy.The inclusion of the radial velocity component will affect the deposit thickness and mass fraction predicted results.The model assumes molecular diffusion as the primary mechanism of transport.The flow field is obtained by solving the momentum equations for the radial and axial velocities using the finite volume method and the SIMPLE method on a colocated structured grid.All the simulations were done under laminar flow conditions.
