CFD of multiphase pipe flow: A comparison of solvers

Pipelines with multiphase flow of gas, oil, and water are commonly used in the oil and gas industry. In the presence of offshore platforms or vessels, the pipeline ends with a vertical riser. A possible new concept is to use a single large diameter pipeline along the sea floor that ends into multiple smaller diameter risers. This concept might...

Optimisation of Flow Distribution for Pipe Pullback in Horizontal Directional Drilling

Horizontal Directional Drilling permits the creation of tunnels which pass beneath rivers and canals to allow the passing of services from one side to the other. The final stage of this process involves lining the tunnel with a plastic or steel pipe. The pipe is pulled inside into the borehole using the same drilling rig that was used to bore...

Prediction of Miscible Fluid-Fluid Displacement in Long Pipelines

In the oil and gas industry, it is crucial that the transport of hydrocarbons through long pipelines occurs in the most efficient and safest way. These pipelines can cover up to several tens to hundreds of kilometres. Hydrocarbons are not the only fluids present within the pipelines, often they are filled with a mixture of oil, gas, water and...
