A Compressible Fluid Flow Model Coupling Channel and Porous Media Flows and Its Application to Fuel Cell Materials
Download2020-01-01
Jarauta, A., Zingan, V., Minev, P., Secanell, M.
A multi-dimensional, compressible fluid flow solver, valid in both channel and porous media, is derived by volume-averaging the Navier-Stokes equations. By selecting an appropriate average density/velocity pair, a continuous, stable solution is obtained for both pressure and velocity. The...

Stickle, Angela, Hogan, James, Kimberley, Jamie, Ramesh, K.T.
Modeling of catastrophic disruption requires understanding the processes of dynamic failure and fragmentation. This paper summarizes current mechanisms and models for dynamic failure, strength, and fragmentation, reviewing these from a mechanics perspective and with an emphasis on making links to...

A comparative study between optimal metal and composite rotors for flywheel energy storage systems
Download2018-11-01
Most recent research on flywheel rotors has focused on high-speed composite rotors as the storage element of the flywheel energy storage system (FESS). Literature research indicates that this is primarily due to the high specific energy of composites compared to metals. However, a quantitative...

Rahman, Md., Mustafizur, Khan, Md., Mohib-Ul-Haque, Ullah, Mohammad, Ahsan, Zhang, Xiaolei, Kumar, Amit
Canada has many isolated communities that are not connected to the electrical grid. Most of these communities meet their electricity demand through stand-alone diesel generators. Diesel generators have economic and environmental concerns that can be minimized by using hybrid renewable energy...

A life cycle assessment of OME (oxymethylene ether) synthesis from biomass-derived syngas as a diesel additive
Download2017-01-01
Mahbub, Nafisa, Oyedun, Adetoyese Olajire, Kumar, Amit, Oestreich, Dorian, Arnold, Ulrich, Sauer, Jörg
The life cycle energy consumption and greenhouse gas (GHG) emission performances of forest biomass-derived oxymethylene ether (OME) synthesis used as a diesel additive are analyzed in this study. OME, a new alternative liquid fuel, has great miscibility with conventional fuels like diesel. OME...

Sperling, F. A. H., Polet, D. T., Flynn, M.R.
Microstructures on insect wings can promote directional drop shedding, and the local orientation of these structures is expected to facilitate drop removal. However, microstructures may exhibit very different orientations at different locations on the wing. Using the march fly Penthetria...

A new ductility exhaustion model for high temperature low cycle fatigue life prediction of turbine disk alloys
Download2011
Zhu, Shun-Peng, Sun, Rui, Zuo, Ming J., Li, Haiqing, Huang, Hong-Zhong
Based on ductility exhaustion theory and the generalized energy-based damage parameter, a new viscosity-based life prediction model is introduced to account for the mean strain/stress effects in the low cycle fatigue regime. The loading waveform parameters and cyclic hardening effects are also...

Mahrous, E., Jarauta, A., Chan, T., Ryzhakov, P., Weber, A.Z., Roy, R.V., Secanell, M.
A particle finite element method (PFEM) based model is proposed to analyze droplet dynamics problems, particularly droplet spreading on solid substrates (wetting). The model uses an updated Lagrangian framework to formulate the governing equations of the liquid. Curvature of the liquid surface is...
