Turbulence Modeling for Heat Transfer to Supercritical Pipe Flows

In the present work, a comprehensive review on different mechanisms affecting heat transfer characteristics of supercritical flows is carried out. The physical mechanism of heat transfer is then further investigated using inhouse DNS data. In addition, RANS simulations of a heated vertical pipe with supercritical CO2 are carried out using...

Transport of suspended particles in turbulent open channel flows

Two experiments are performed in order to investigate suspended sediment transport in a turbulent open channel flow. The first experiment used particle image velocimetry (PIV) to measure the fluid velocity with a high spatial resolution, while particle tracking velocimetry (PTV) was used to measure the velocity of individual sediment particles....

Particle Sedimentation in Wall-Bounded Turbulent Flows

In this work, a comparison between the results of point-particle direct numerical simulations and PIV/PTV experiments of a particle-laden horizontal channel flow is presented. The numerical simulations were preformed trying to mimic as much as possible the experimental conditions. The accuracy of the point-particle approach was evaluated by...
