TL;DR: In this article, experimental data and results of direct numerical simulations are reviewed in order to show that premixed combustion can change the basic characteristics of a fluctuating velocity field (the so-called flame-generated turbulence) and the direction of scalar fluxes (the countergradient or pressure-driven transport) in a turbulent flow.

TL;DR: In this paper, the current status of China's road transport sector in terms of vehicles, infrastructure, energy use and emissions is presented, and mitigation measures implemented and those that can reasonably be expected to be adopted in the near future are analysed.

TL;DR: The population balance equation (PBE) was originally developed and investigated mainly in the context of spatially homogeneous systems as mentioned in this paper, and has been applied to a variety of flow problems such as sooting flames and turbulent precipitation, but significant issues regarding its appropriate coupling with CFD pertain especially in the case of turbulent flow.
