Journal ArticleDOI
Thermal and mechanical properties of the near-surface layers of comet 67P/Churyumov-Gerasimenko
Tilman Spohn,Jörg Knollenberg,A. Ball,Marek Banaszkiewicz,Johannes Benkhoff,Matthias Grott,J. Grygorczuk,C. Hüttig,Axel Hagermann,G. Kargl,Erika Kaufmann,Norbert I. Kömle,Ekkehard Kührt,Konrad J. Kossacki,Wojciech Marczewski,Ivanka Pelivan,R. Schrödter,Karsten Seiferlin +17 more
TL;DR: Using data from the MUPUS instrument package gathered at the Philae landing site Abydos on comet 67P/Churyumov-Gerasimenko, the diurnal temperature to vary between 90 and 130 K and a sintered near-surface microporous dust-ice layer with a porosity of 30 to 65% is consistent with the data.
Journal ArticleDOI

Proffe,Frank Scholten,Daniela Tirsch,Mikhail A. Kreslavsky,Emile Remetean,F. Souvannavong,B. Dolives +19 more
TL;DR: ROLIS images of the Agilkia site reveal a photometrically uniform surface covered by regolith composed of debris and blocks ranging in size from centimeters to 5 meters, and modeling suggests that abrasion driven by airfall-induced particle “splashing” is responsible for the observed formations.

Can We Ever Rely on Results from Wall-Bounded Turbulent Flows without Direct Measurements of Wall Shear Stress?
Hassan M. Nagib,Chris Christophorou,Jean-Daniel Rüedi,Peter A. Monkewitz,Jens M. Österlund,Steve Gravante,Kapil Chauhan,Ivanka Pelivan +7 more
TL;DR: In this article, three techniques for measuring skin friction in two-dimensional turbulent wall-bounded shear flows are presented: oil-film interferometry, hot wires mounted near the wall, and surface hot-film sensors based on MEMS technology.
