The Effect of Flow-Induced Oil-Water Emulsions on Pressure Drop
(2000)In the oil production industry, crude oil is usually produced together with water from the reservoirs, and the immiscible mixtures of oil and water result in emulsions flow in the transporting pipelines. In this research ... -
Simulation of the orthogonal metal cutting process using an arbitrary Lagrangian–Eulerian finite-element method
(Science Direct, 2000-06)Two different finite-element formulations, the Lagrangian and the Eulerian, have been used extensively in the modeling of the orthogonal metal cutting process. Each of these formulations has some disadvantages that make ... -
