Interface Investigation of Core-annular Flow

The transport of highly-viscous oil in the core-annular flow regime in a horizontal pipe is investigated with a numerical simulation study. In this flow type the viscous oil is lubricated by a water annulus along the pipe wall. The Launder-Sharma low-Reynolds number k-ε turbulence model is used with the Volume-of-Fluid solver in interFOAM. Three...

Analysis of a Hybrid RaNS-BEM Method for Predicting Ship Power

Predicting the equilibrium between a ship’s required thrust and resistance is a complicated problem. Shipyards have to pay big penalties when a ship does not run at its design speed at a specified required power. An accurate prediction of the ship’s self-propulsion point is thus of huge importance. In the determination of the self-propulsion...
