Push or Pull, How Does Silk Flow?

J. Sparkes [1],
[1] University of Sheffield, Sheffield, UK

Silk is one of the longest used and most recognizable textiles that we, as a society, use regularly. We see it as a luxury good, worn as an indicator of success and value. However, despite mankind having domesticated and farmed silkworms for millennia, we still know relatively little ... En savoir plus

Combining Multiphysics Modeling and Solution Thermodynamics Using M4Dlib, an External Library

T. Marin-Alvarado [1],
[1] M4Dynamics, Toronto, ON, Canada

An external library, M4Dlib [1], has been developed to solve multiphysics problems coupled to solution thermodynamics. This approach extends the local equilibrium concept[2] to multiphysics modeling by incorporating a full Gibbs energy minimization routine at each numerical node to ... En savoir plus

Simulation of the Cooling and Phase Change of a Melt-Cast Explosive

W. Sanhye [1], C. Dubois [1], P. Pelletier [2], I. Laroche [2],
[1] Department of Chemical Engineering, École Polytechnique de Montréal, Montréal, QC, Canada
[2] General Dynamics Ordnance and Tactical Systems-Canada Inc., Repentigny, QC, Canada

Introduction Numerical modeling of melt-casting is becoming a popular tool for the energetic materials and explosives industry. Compared to traditional metal casting, the cooling cycle for explosive melts is significantly longer because of their high Prandtl numbers [1]. Improving the ... En savoir plus

Direct Pore-scale Modeling of Two-phase Flow Through Natural Media

I. Bogdanov, J. Kpahou, and A. Kamp
Open and Experimental Centre for Heavy Oil (CHLOE)
University of Pau
Pau, France

Direct numerical simulation of single- and two-phase flow in real pore systems is addressed in our paper. The X–ray computed micro-tomography technique has been applied first to reconstruct in details a real pore space of a subcentimetric sample. Making use of dedicated software (ScanIP) ...
