Progress on theoretical issues in modelling turbulent transport
Nuclear Fusion, 2013We discuss theoretical progress in turbulent transport modelling in tokamaks. In particular, we address issues that the conventional quasilinear type calculation cannot confront, such as (i) the nature of turbulence in the edge-core coupling region of tokamaks (i.e.

Modelling of Turbulent Transport in Laser Melt Pools
Volume 1: Fora, Parts A, B, C, and D, 2003In this paper, we present a modified k-ε model capable of addressing turbulent molten metal-pool convection in the presence of a continuously evolving phase-change interface during a laser melting process. The phase change aspects of the present problem are addressed using a modified enthalpy-porosity technique.

Turbulence Models for Sediment Transport Engineering
2008In problems of civil engineering interest, sediment transport invariably occurs under turbulent-flow conditions. Traditional discussions (ASCE Manual 54; see also Chapter 2) of turbulence models have, however, been mainly restricted to the problem of determining the vertical distribution of suspended sediment in the simplest case of uniform channel ...

Prediction of turbulent flow in annular ducts with differential transport model of turbulence
Wärme- und Stoffübertragung, 1974In general, flow in an annulus will be strongly asymmetric because of unequal curvatures and, possibly, dissimilar texture of the two boundaries. As a result, the turbulent flow structure in such geometries possesses a number of features which can not satisfactorily be accounted for with a simple model of turbulence.

Turbulence Transport Modeling and PSP Observations
2019The Parker Solar Probe (PSP) has made two orbits of the Sun since its launch in August 2018. The PSP achieved its first orbit perihelion on November 6, 2018, reaching a heliocentric distance of about 0.16 au. Here, we study the evolution of fully developed turbulence associated with the slow solar wind along the PSP trajectory between ~ 0.16 au and ~ 0.
