Numerical Investigation of Short Elliptical Twisted Tube for Reduced Fouling Rate in Steam Cracking Furnaces

Bruce Indurain y Urricelqui, François Beaubert, David Uystepruyst, Sylvain Lalot, Mathieu Couvrat

In the steam cracking industry of natural gas or naphtha, fouling of tubular heat exchangers by cokes is a major issue. This growing carboneous layer has two major negative effects: 1) it increases pressure drop and 2) reduces heat transfer from the tube wall to the processed fluid. Using the open-…

Approach for CAD model reconstruction basing on 3D points insertion and surface approximation

Aicha Ben Makhlouf, Nessrine Elloumi, Borhen Louhichi, Dominique Deneux

Reverse engineering (RE) consists in the reconstruction of a geometric model of a 3D object from a set of points, a mesh or a 3D triangulation. This model is a combination of geometric primitives (cylinders, planes, spheres, etc.) and complex surfaces (B-Spline, NURBS…) defined by parameters that…

CO2 reduction in a common rail direct injection engine using the combined effect of low carbon biofuels, hydrogen and a post combustion carbon capture system

Edwin Geo Varuvel, Shanmugam Thiyagarajan, Ankit Sonthalia, T. Prakash, Sary Awad, Fethi Aloui, Arivalagan Pugazhendhi

The transportation sector is a major emitter of carbon dioxide emissions. It is a known fact that carbon dioxide is the cause of global warming which has resulted in extreme weather conditions as well as climate change. In this study a combination of different methods of expediting the CO2 emission…

Experimental analysis to reduce CO2 and other emissions of CRDI CI engine using low viscous biofuels

Edwin Geo Varuvel, Guillaume Fol, Fethi Aloui, Shanmugam Thiyagarajan, M. Jerome Stanley, Ankit Sonthalia, Kathirvel Brindhadevi, C. G. Saravanan

It is the need of the hour to quell the enormous demand of fossil fuels by extending the horizon towards Low Viscous Biofuels. An experimental investigation was carried out to study the performance of the diesel engine, its combustion behaviour and emission aspects while operating it with biofuels…

To the self and beyond: Arousal and functional connectivity of the temporo-parietal junction contributes to spontaneous sensations perception

Sara Salgues, Gaën Plancher, Laurence Jacquot, Janick Naveteur, Lison Fanuel, Germán Galvez-Garcia, George A. Michael

The temporoparietal junction (TPJ), along with the anterior insula (AI) and the extrastriate body area (EBA), play a major part in embodiment and self-awareness. However, these connections also appear to be frequently engaged in arousal and attentional processing of external events. Considering…

Time-temperature superposition in viscoelasticity and viscoplasticity for thermoplastics

Vincent Dorleans, Rémi Delille, Delphine Notta-Cuvier, Franck Lauro, Éric Michau

The use of thermoplastics in the automotive industry is continuously increasing. Design of parts require the characterization and numerical modelling of thermo-mechanical behaviour of those materials under wide strain rate (0–300 s−1) and temperature ranges (−30 °C to +85 °C). Large and costly…

Galling phenomena in metal forming

Kuniaki Dohda, Masahito Yamamoto, Chengliang Hu, Laurent Dubar, Kornel F. Ehmann

Galling phenomena in metal forming not only affect the quality of the engineered surfaces but also the success or failure of the manufacturing operation itself. This paper reviews the different galling conditions in sheet and bulk metal forming processes along with their evolution and the effects…

Service Oriented, Holonic and Multi-Agent Manufacturing Systems for Industry of the Future

Theodor Borangiu, Damien Trentesaux, Paulo Leitão, Olivier Cardin, Samir Lamouri

The scientific theme of the book concerns “Manufacturing as a Service (MaaS)” which is developed in a layered cloud networked manufacturing perspective, from the shop floor resource sharing model to the virtual enterprise collaborative model, by distributing the cost of the manufacturing…

Cascade Descriptor Observers: Application to Understanding Sitting Control of Persons Living With Spinal Cord Injury

Hajer Srihi, Thierry-Marie Guerra, Tran Anh-Tu Nguyen, Philippe Pudlo, Antoine Dequidt

People with spinal cord injury (SCI) suffer from a drastic reduction in sitting stability which negatively impacts their postural control. Thus, sitting balance becomes one of the most challenging everyday exercises. To better understand the consequences of this pathology, we have to work with high…
