Characteristics of Methane Hydrate Formation in Artificial and Natural Media

Zhang, Peng; Wu, Qingbai; Yang, Yuzhong - In: Energies 6 (2013) 3, pp. 1233-1249

The formation of methane hydrate in two significantly different media was investigated, using silica gel as an artificial medium and loess as a natural medium. The methane hydrate formation was observed through the depletion of water in the matrix, measured via the matrix potential and the...

Memory of recessions.

Cross, Rod; McNamara, Hugh; Pokrovskii, Alexei - Economics Department, University of Strathclyde - 2010

This paper reviews the evidence on the effects of recessions on potential output. In contrast to the assumption in mainstream macroeconomic models that economic fluctuations do not change potential output paths, the evidence is that they do in the case of recessions. A model is proposed to...

Multiple-relaxation-time lattice Boltzmann modeling of incompressible flows in porous media

Liu, Qing; He, Ya-Ling - In: Physica A: Statistical Mechanics and its Applications 429 (2015) C, pp. 215-230

In this paper, a two-dimensional eight-velocity multiple-relaxation-time (MRT) lattice Boltzmann (LB) model is proposed for incompressible porous flows at the representative elementary volume scale based on the Brinkman–Forchheimer-extended Darcy model. In the model, the porosity is included...

Influence of wavy wall and non-uniform heating on natural convection heat transfer and entropy generation inside porous complex enclosure

Bhardwaj, Saurabh; Dalal, Amaresh; Pati, Sukumar - In: Energy 79 (2015) C, pp. 467-481

The present work numerically analyses the heat transfer and entropy generation characteristics in a two-dimensional porous right-angled triangular enclosure with undulations on the left wall. The enclosure is heated sinusoidally from the bottom wall, while the left wall is maintained at a...
