Ducted fuel injection: A new approach for lowering soot emissions from direct-injection engines
Charles J. Mueller,Christopher W. Nilsen,Daniel Ruth,Ryan K. Gehmlich,Lyle M. Pickett,Scott A. Skeen +5 more
TL;DR: In this article, the authors proposed a new mixing-enhancement strategy for emissions reduction, ducted fuel injection, which injects fuel along the axis of a small cylindrical duct within the combustion chamber, to enhance the mixture in the auto-ignition zone relative to a conventional free-spray configuration.

Bubble pinch-off in turbulence.
TL;DR: The pinch-off of a bubble in turbulence is investigated and it is demonstrated that the turbulent flow field freezes during the pinching process, opening the route for a self-similar collapse close to the one predicted for unperturbed configuration.

- 25 Jun 2017
TL;DR: In this article, the seasonal variability of photovoltaic soiling losses over a 12-month period for 15 soiling stations deployed in the USA was investigated, and a new parameter able to rank the sites according to the cumulative losses occurring over 3-and 6-month periods was presented.

The effect of nonlinear drag on the rise velocity of bubbles in turbulence
TL;DR: In this article, the authors investigate how turbulence in liquid affects the rising speed of gas bubbles within the inertial range and find that the bubble mean rise velocity that drastically reduces the mean rise speed.
