Structural Design from Reclaimed Material Sauvabelin – The Never-Ending Story
This thesis is developed as part of the final year project that must be completed to obtain the MCs degree in Civil Engineering at EPFL. It follows up the pre-study project carried out during the last semester of the course. The environmental crisis that o ...
2022Cross verified independent measurements of correlated bubble property distributions as part of the scale-up of a catalytic bubbling fluidized bed reactor
Methanation can be applied as part of a Power-to-Gas (PtG) concept to store renewable electricity. Using a catalytic bubbling fluidized bed (BFB) methanation reactor allows a flexible and economic operation. Properties of bubbles rising through the fluidiz ...
EPFL2022Theoretical and Experimental Investigation of a Small-scale, High-speed, and Oil-free Radial Anode Off-gas Recirculation Fan for Solid Oxide Fuel Cell Systems
Jan Van Herle, Jürg Alexander Schiffmann, Patrick Hubert Wagner
The Laboratory for Applied Mechanical Design (LAMD) designed, manufactured, and experimentally tested a novel recirculation fan for a 10 kWe solid oxide fuel cell (SOFC). The fan uses oil-free bearings, more specifically herringbone-grooved journal and spi ...
2020On the Influence of an Elevated Terrain on the Grounding Resistance of a Vertical Rod
Marcos Rubinstein, Antonio Sunjerga
In this paper, we analyze the grounding resistance of a vertical grounding rod located in an elevated terrain. Tall structures such as wind turbines and mobile phone base stations are often installed in remote and hilly locations to gain more power or to f ...
IEEE2019Effects of spatial variation of cluster entry friction on hydraulic fracture propagation in multistage fracturing
Brice Tanguy Alphonse Lecampion, Dmitry Nikolskiy
In this contribution, we explore different aspects of the multi-stage fracturing process such as stress interaction between growing hydraulic fractures, perforation and near-wellbore tortuosity effects as well as the wellbore flow dynamics using a fit-for- ...
2019Modeling of Simultaneous Propagation of Multiple Blade‑Like Hydraulic Fractures from a Horizontal Well
Brice Tanguy Alphonse Lecampion, Dmitry Nikolskiy
We explore different aspects of the multi-stage fracturing process such as stress interaction between growing hydraulic fractures, perforation friction, as well as the wellbore flow dynamics using a specifically developed numerical solver. In particular, g ...
2019Fine DNA structure revealed by constant height frequency modulation AFM imaging
Giovanni Dietler, Dusan Vobornik, Andrea Cerreta
Few examples of sub nanometer resolution on biomolecules can be found in literature. In particular, AFM experiments on DNA mostly fail to show the double helical groove periodicity, and so far such a feat was only achieved in liquid. Here we describe a met ...
Elsevier2013Observations, theory, and modeling of the differential accumulation of Antarctic megadunes
Antarctic megadunes are characterized by significant spatial differences in accumulation rate, with higher accumulation on the windward side and near-zero accumulation on the lee side. This leads to spatial differences in physical properties of snow and su ...
Amer Geophysical Union2013FM-AFM constant height imaging and force curves: high resolution study of DNA-tip interactions
Giovanni Dietler, Dusan Vobornik, Livan Bladimir Alonso Sarduy, Andrea Cerreta
Interaction of the atomic force microscopy (AFM) tip with the sample can be invasive for soft samples. Frequency Modulation (FM) AFM is gentler because it allows scanning in the non-contact regime where only attractive forces exist between the tip and the ...
Wiley-Blackwell2012The autocorrelation function for island areas on self-affine surfaces
Jean-François Molinari, Guillaume Anciaux, Srinivasa Babu Ramisetti
The spatial distribution of regions that lie above contours of constant height through a self-affine surface is studied as a function of the Hurst exponent H. If the surface represents a landscape, these regions correspond to islands. When the surface repr ...
