Influence of Axial Conduction in the Design of a Compact Recuperator for Catalytic Combustor Based Portable Power Generation new

A. N. Smith[1], H. Nochetto[2], C. M. Waits[2]
[1]U.S. Naval Academy, Annapolis, MD, USA
[2]U.S. Army Research Lab, Adelphi, MD, USA

Catalytic micro-combustor represents an exciting area of research for portable power generation. Extensive research is being currently conducted on the design of the reactor and catalyst selection [1]. However another critical element of the design will be a recuperator to minimize ... Read More

Model of Natural Convection above Horizontal and Inclined Plates

I. Khan [1], V. Tsitsopoulos [2], J. Dold [3],
[1] University of Central Lancashire, Preston, United Kingdom
[2] AMEC, London, United Kingdom
[3] University of Manchester, Manchester, United Kingdom

The boundary layer flow above an isothermal flat plate inclined at a small angle to the horizontal is analyzed. Inclination effects are initially investigated as a perturbation to the horizontal flow by obtaining a fourth order series solutions valid near the leading edge of the plate ... Read More

Level-set simulation of impingement and spreading of micro-sized non-Newtonian droplet

Hai Long Liu [1], Xuefeng Shen [1], Yu Cao [1], Zhiwei Liu [1], Jiancheng Wang [1], Tianhao Zhang [1], Yuerou Wang [1],
[1] Jiangsu University, Zhenjiang, Jinagsu Province, China

The spreading dynamics of micro-sized droplet impact on solid surface is not only an interesting phenomenon observed in nature, but also plays a crucial role in a variety of engineering applications. Most fluids used in industries always contain various kinds of additives such as ... Read More

Reliability Evaluation for Static Chamber Method at Landfill Sites

H. Ishimori[1], K. Endo[1], and M. Yamada[1]
[1]National Institute for Environmental Studies, Tsukuba, Ibaraki, Japan

In this study, COMSOL Multiphysics was used for the reliability evaluation for static chamber method at landfill sites. Static chamber method, which measures landfill gas emission fluxes, is widely used at landfill sites for the monitoring of greenhouse gas emission such as methane and ... Read More

Impact of Velocity and Interfacial Tension on the Performance of Horizontal Wells in Gas Condensate Reservoirs

P. Ghahri, M. Jamiolahmady, and M. Sohrabi
Heriot Watt University, Edinburgh, United Kingdom

Drilling horizontal wells (HWs) has recently received renewed attentions with the increasing trend in exploitation of tight gas reservoirs. An accurate estimation of productivity of such systems using a numerical simulator is a challenging task, because its 3D simulation requires a fine ... Read More

Study of Particle Collection Using Magnets

M. D. Cheng [1],
[1] Oak Ridge National Laboratory, Oak Ridge, TN, USA

Airborne particles or aerosols are an unstable system with distributed properties among its individual particulate members. Its fundamental property such as particle size, composition, electrical conductivity, magnetic susceptibility, and morphology could change in response to ... Read More

Rheological Behaviour of Biphasic Material

P. Lamy-Bracq[1], J. Leroy[2], and C. Coulouarn[1]
[1]NEXTER Munitions, Bourges, France
[2]ENSI Bourges, Bourges, France

The rheological behaviour of a biphasic material is quite difficult to model because of the difficulties to represent the evolution of the space position of each solid particle in the solid matrix. The first part of this study consider an equivalent material by homogeneisation method. ... Read More

Blistering of Industrial Floors on Concrete Substrate: The Role of Air Overpressure

P. Devillers[1], S.V. Aher[2], G. Fau[3], B. Tranain[3], and C. Buisson[1]
[1]Centre des Matériaux de Grande Diffusion, Ecole des Mines d’Alès, France
[2]Department of Civil Engineering, Indian Institute of Technology Kanpur, Kanpur, Uttar Pradesh, India
[3]Centre Scientifique et Technique du Bâtiment, Champs sur Marne, France

A three dimensional COMSOL Multiphysics, transient analysis, diffusion model has been adopted to model the transfers of water in the industrial concrete floors. To take into account the different initial saturation levels at the different levels of the slab, the model is divided into ... Read More

Permeability in Fragmented Materials and its Application to Underground Mining

S. Palma [1], R. Castro [1], A. Hekmat [1],
[1] Mining Engineering Department, Block Caving Laboratory, University of Chile, Santiago, Chile

The block caving mine is considered by the mining industry as one of the natural replacements of the current open cut mines in the near future. The block caving technique is based on the extraction of small broken rocks, created by blasted initially large solid rocks, and the fracture of ... Read More

Development of an Oxygen-Conserving Mask for Pediatric Patients in Low-Resource Settings

D. Gasperino [1]
[1] Intellectual Ventures Laboratory, Bellevue, WA, USA

Worldwide, the leading cause of mortality in children is acute respiratory infection, primarily associated with pneumonia. One of the essential tools used to treat life-threatening hypoxemia due to pneumonia is the appropriate use of supplemental oxygen. While oxygen therapy is ... Read More
