Trace metal pollution in the Scheldt estuary - a statistical approach to estimate the metal partitioning coefficient for a suite of metals

Trace metals appear in estuarine systems in two forms: dissolved and particulate. <br/>Describing the partitioning between these two forms is done by a coefficient, K_d, which relies on a number of environmental parameters, such as the salinity of the water and the seasonally dependent biological activity. Although this coefficient is known to...

Ignition modeling in methane-oxygen rocket engines: Design and modeling of a methane-oxygen rocket engine igniter using reacting flows with computational fluid dynamics

The influence of using different chemistry model and different chemical kinetics schemes on modeling combustion inside a rocket engine igniter are investigated. An igniter for a LOX/CH4 rocket engine is designed and a CFD model is developed which is used to model the designed igniter. Verification and validation methods are discussed.<br/><br/>...
