Shell – Numerical-physical Modeling of Miscible Fluids in Pipeline Transport
01-12-2016 - In the oil and gas industry hydrocarbons are transported through long pipelines under various conditions. This transport process generally involves multiple chemical components present in multiple phases (oil, gas, water). The mathematical modeling and simulation of these problems is often done with one-dimensional models that treat the phases as immiscible. However, a particular case that
TNO – Stress Fields Inside of a Neck for more Accurate Crash Analysis
18-05-2016 - Background As a material (typically, a metal) is stretched, it can reach a point where all of the strain (deformation) is concentrated in just one area. For example, notice in the figure below how the material has become very narrow across a short length in the specimen which was initially cylindrical. This condition is called
Albemarle – Mixing and Modelling: How Mathematics May Mix Molecules
05-07-2016 - Introduction Albemarle is a big chemical concern with about 3700 employees and many plants worldwide. It is a manufacturer of polymers and fine chemicals, including additives and intermediates used in agricultural and cleaning products, drilling compounds, etcetera. Since mixing of different chemical compounds is one of its core techniques, Albemarle Research in Amsterdam (former Akzo
KWR – Predicting the Removal Performance of Activated Carbon Filters in Water Treatment
17-12-2018 - In the Netherlands, about one-third of the drinking water is produced out of surface water that may contain all kinds of micropollutants (pesticides, pharmaceuticals, industrial compounds). A large fraction of these drinking water production sites uses filtration by sorption onto activated carbon as an important barrier for micropollutants that are present in the water. The
