Radiation Heat Transfer in Imaging Infrared Spectrometer

A. Jhaveri [1], M. Kushhare [1], A. Bhargav [1],
[1] Indian Institute of Technology Gandhinagar, Gandhinagar, Gujarat, India.

Imaging Infrared Spectrometer (IIRS) is a Hyperspectral optical imaging instrument which measures the spectra of a scene in high resolution within spectral bands covering Near Infrared (NIR) to Mid Infrared (MIR) regions. Radiation entering the spectrometer assembly governs the ... En savoir plus

Numerical Simulation: Field Scale Fluid Injection to a Porous Layer in Relevance to CO₂ Geological Storage

S. Kim[1], S. A. Hosseini[1], S. D. Hovorka[1]
[1]Bureau of Economic Geology, The University of Texas at Austin, Austin, TX, USA

CO₂ geological storage can help to provide a “bridge” from a fossil-fuel dependent system to a more diversified energy portfolio. Pressure monitoring for an injection zone (IZ) and an above-zone monitoring interval (AZMI) has been under operation at a field-scale CO₂ injection site, ... En savoir plus

A COMSOL-based 2D Self-Consistent Microwave Plasma Model

A. Berthelot [1], A. Bogaerts [1],
[1] PLASMANT Group, University of Antwerp, Belgium

In this paper, we present a 2D axisymmetric self-consistent plasma fluid model for microwave plasmas operating in argon. The model was developed using COMSOL Multiphysics and its Plasma Module. Plasma, flow, heat and electromagnetic equations solved self-consistently. The effect of the ... En savoir plus

Digital Microfluidic Droplet Adapter for Interconnection of Biochips

R. Zhu[1], X. Xiong[2], P. Patra[1], C. Jin[1], J. Hu[3]
[1]Department of Biomedical Engineering, University of Bridgeport, Bridgeport, CT, USA
[2]Department of Electrical & Computer Engineering, University of Bridgeport, Bridgeport, CT, USA
[3]Department of Mechanical Engineering, University of Bridgeport, Bridgeport, CT, USA

In this research, we use the COMSOL Multiphysics® software to design and simulate a digital microfluidic droplet adapter for board-level biochip integration. Digital Microfluidic Biochip (DMFB) has gained tremendous research interest in recent years due to its importance in Lab-on-a-Chip ... En savoir plus

Chiral surface plasmon polaritons on metallic nanowires

S. Zhang
Institute of Physics CAS
Beijing
China

Chiral SPPs can be generated by linearly polarized light incident at the end of a nanowire, exciting a coherent superposition of three specific nanowire waveguide modes. Chirality is preserved in the emitted photons, creating a subwavelength ¼ wave plate. En savoir plus

Modeling two-phase flow in strongly heterogeneous porous media

Z. Huang
China University of Petroleum, Research Center for Oil & Gas Flow in Reservoir, Qingdao City, China

Modeling Two-phase flow through strongly heterogeneous porous media is of importance in many disciplines including petroleum industry, hydrology etc. There are, however, still some challenges in numerical simulation of such flow problems especially the flows in fractured porous media and ...

[1] Le Cnam, Paris, France
[2] Ecole des Ponts, Champs-sur-Marne, France
[3] Bouygues Construction, Saint-Quentin-en-Yvelines, France

This work investigates the possibility of thermal activation of future tunnels to heat and/or cool the surface buildings or infrastructure such as subways stations. The principle is to insert pipes in the tunnel lining segments, which are connected to a geothermal pump. A heat transfer ... En savoir plus

Modeling Flow and Deformation During Salt-Assisted Puffing of Single Rice Kernels

T. Gulati[1], A. K. Datta[1]
[1]Department of Biological & Environmental Engineering, Cornell University, Ithaca, NY, USA

Puffing of biomaterials involves mass, momentum and energy transport along with large volumetric expansion of the material. Development of physics-based models that can describe heat and moisture transport, rapid evaporation and large deformations can help understand the puffing process. ... En savoir plus
