Results of the Tenth Challenge

Seven entries were received from: a) Irais Valencia-Jaime, Brittany Gonzalez, Solene Bechelli, Steve Groven, Caroline Desgranges, and Jerome Delhommelle (North Dakota); b) Richard A. Messerly and Michelle C. Anderson (NIST) and S. Mostafa Razavi and J. Richard Elliott (Akron); c) Zheng Gong and Huai Sun (Shanghai Jiao Tong University); d) Nilolay Kondratyuk and Vasily Pisarev (Joint Institute for High Temperatures RAS, Higher School of Economics, Moscow Institute of Physics and Technology); e) Benjamin Levy and Carmelo Herdes (University of Bath); f) Lingru Zheng, J.P. Martin Trusler, Fernando Bresme, and Erich A. Müller (Imperial College London); and g) Marco A. Galvani Cunha and Mark O. Robbins (Johns Hopkins).

In general, the predictions by MD simulation of ambient pressure viscosity, eta0, and of the reciprocal asymptotic isoviscous pressure coefficient,  alpha*, were satisfactory for evaluation of film-forming capability. Additionally, the prediction by MD simulation of the piezoviscous response at Hertz pressure could be useful for improved evaluation of friction.

Based on the quality of their predictions compared to experiment, the team from Johns Hopkins was named Champions of the 10th Industrial Fluid Properties Challenge. The team from the Joint Institute for High Temperatures RAS came in second place.

Manuscripts from the 10th Challenge will be published in Fluid Phase Equilibria in 2019.
