A Black-Oil Model for Primary and Secondary Oil-Recovery in Stratified Petroleum Reservoirs

A. Dollari [1], C. Chatzichristos [1], A. Yiotis [1],
[1] National Center for Scientific Research Demokritos, Greece

Black-oil simulators are commonly used in petroleum reservoir engineering for the prediction of oil production, especially during the earlier stages of oil-field exploitation, while also serving to guide pressure maintenance strategies in the longer term. Such models account for fluid ... En savoir plus

Sensitivity Estimation of Permanent Magnet Flowmeter

V. Sharma[1], S. K. Dash[1], G. Vijaykumar[1], B. K. Nashine[1], B. Krishnakumar[1], P. Kalyanasundaram[1], and G. Vaidyanathan[1]
[1]Fast Reactor Technology Group, Indira Gandhi Centre for Atomic Research, Kalpakkam, Tamil Nadu, India

Permanent Magnet Flowmeter (PMFM) is a non invasive device, which is used to measure the flow of electricallyconducting sodium in Fast Breeder Reactor Circuits. PMFM works on the principle of generation of motional EMF by magnetic forces exerted on the charges in a moving conductor. In ... En savoir plus

Gas Treatment by Induction Heating: Process Evaluation via Homogenized Modelling Approach

M.Dumont¹, A. Essyed², X.H. Pham², L. Truong-Phuoc², J.-M. Nhut², C. Pham-Huu²
¹EMDPI, Jam Consulting, Grenoble, France
²ICPEES, UMR 7515 CNRS-University of Strasbourg, Strasbourg, France

Induction heating (IH) [1] is an electrically driven process useful for decarbonization of the industry. It can be used for electrification of chemical processes to replace traditional heating with gas burner and avoid CO2 emission. This kind of process can be used to heat efficiently ...

Application of Solution Mapping to Reduce Computational Time in Actively Cooled Power Electronics

K. Lowe [1,2], and Rao V. Arimilli[2]
[1]Oak Ridge National Laboratory, Oak Ridge, TN, USA
[2]Department of Mechanical, Aerospace, and Biomedical Engineering, University of Tennessee, Knoxville, TN, USA

In some power electronic applications the available coolant temperature is close to maximum and controlling operating temperature becomes more challenging, for which new thermal management schemes must be considered. COMSOL predicts the 3D fluid behavior and 3D temperature distribution ... En savoir plus

Flow Optimization of a MVHR Combined with an Exhaust Air Heat Pump by Means of CFD Simulation

F. Ochs [1], M. Bianchi Janetti [1], M. Romani [2],
[1] University of Innsbruck, Unit Energy Efficient Buildings, Austria
[2] Galletti Group, Italy

In the framework of the Austrian FFG project SaLüΗ!, a compact mechanical ventilation system with integrated micro-heat pump was developed. The aim was a high level of prefabrication and a compact design allowing for installation also in small flats, e.g. into the façade. Due to the ... En savoir plus

Design and Simulation of Indigenous Roll-over Sensor for Four-Wheeler Automobiles

Piyush Raj [1], Adarsh G Datta [1], Vishnu Kumar [1],
[1] Indian Institute of Science, Bangalore, Karnataka, India

In India, more than 150,000 people are killed each year in traffic accidents, according to the Ministry of Road Transport and Highways 2016 report. That’s about 400 fatalities a day, which is far higher than in developed auto markets like the US which, in 2016, logged about 40,000 a ... En savoir plus

Numerical Simulation of Coupled Fluid-Solid Interaction in Digital Rock Samples

V. Das [1], T. Mukerji [1], G. Mavko [1],
[1] Stanford University, Stanford, CA, USA

Digital rock physics (DRP) is an emerging field where a rock sample is imaged, relevant physical processes are simulated numerically on the digital rock sample, and the numerical solutions are used for understanding and interpreting the rock in different in-situ conditions. The use of ... En savoir plus

Numerical and Experimental Study of Flow, Heat Transfer and Concentration in a Scaled-up Fuel Cell Anode Channel Model

J. C. Torchia-Nüñez[1], and J.G. Cervantes-de-Gortari[1]

[1]Department of Thermal Engineering, National University of Mexico, UNAM, Mexico City, Mexico

Flow, concentration and temperature fields are studied with numerical and experimental methods inside a scaled-up fuel cell anode channel model. The low aspect ratio channel has a porous medium as the inferior wall where a mixing of different pH solutions occurs. Chromatic change of ... En savoir plus
