Development of the Mechanical Properties of an Ultra-High Performance Fiber Reinforced Concrete (UHPFRC)

Eugen Brühwiler, Emmanuel Denarié, Marco Viviani, Katrin Habel

Knowledge of the mechanical properties, i.e. strength, stiffness and deformation capacity, of cementitious materials at any arbitrary time is fundamental for operations such as removal of formwork, prestressing or cracking control. This paper presents a st ...

Supercritical reaction calorimetry: A novel route to supercritical fluid reaction monitoring

Thierry Meyer, Charalampos Mantelis, Frédéric Lavanchy

Supercrit. fluids (SCFs) were intensively studied in the last decade as alternative, environment-friendly benign reaction solvents. A new anal. technique was derived from a combination of classical heat flow reaction calorimetry and the supercrit. fluid te ...

Process design of Synthetic Natural Gas (SNG) production using wood gasification

François Maréchal, Claude Friedli, Alexis Joseph Duret

The process design of a 10 to 20MWth Synthetic Natural Gas (SNG) production process from wood has been performed. Combining process modeling and process integration techniques, this study proceeds via the following stages: • thermodynamic modeling: mass, e ...

How reliable are thermodynamic feasibility statements of biochemical pathways?

Urs von Stockar

The driving force for organo- or lithotrophic growth as well as for each step in the metabolic network is the Gibbs reaction energy. For each enzymic step it must be neg. Thermodn. contributes therefore to the in-silico description of living systems. It ma ...

Introductory Thermodynamics

Pierre Infelta

The fundamental aspects of classical thermodynamics are presented in a simple compact way. The equations derived are illustrated by numerous (111) examples, often direct application of the relations just obtained. The (four) laws of thermodynamics are pres ...

A microreactor-based system for the study of fast exothermic reactions in liquid phase: characterization of the system

Peter Ryser, Thomas Maeder, Francis Stoessel, Marie-Agnès Schneider

A new system combining a microreactor and a microcalorimetric chip was investigated. The small size of the microreactor channel permits maintaining isothermal conditions necessary for the kinetic characterization of highly exothermic reactions. These condi ...

Wall Friction and Boundary Layer Development in the Cone of a Francis Turbine Scale Model

François Avellan, Elena Berca

To characterize the boundary layer development, in the cone of the Francis turbine, wall friction and velocity measurements are performed. The mean wall friction measurements evidence the increasing risk of the boundary layer separation at the cone wall wi ...

A historically correct didactic first step in the quantum world: stressing the interplay of relativity, thermodynamics and quantum physics

Giorgio Margaritondo

Quantum physics is the backbone of modem science: therefore, a correct first step is essential for students' success in many different disciplines. Unfortunately, many didactic approaches are still complicated, potentially confusing and often historically ...

Thermal modeling of a small anode supported solid oxide fuel cell

François Maréchal, Daniel Favrat, Jan Van Herle, Diego Larrain

A combined thermal and simple kinetic model is applied to a small single solid oxide fuel cell (SOFC, 20 cm2 square cell of anode supported electrolyte with 1 cm2 active area). The aim was to compute the temperature field to analyze the operating condition ...

Breathing sediments: The control of diffusive transport across the sediment-water interface by periodic boundary-layer turbulence

Alfred Johny Wüest

We performed combined in situ measurements of bottom boundary-layer turbulence and of diffusive oxygen fluxes at the sediment-water interface in a medium-sized mesotrophic lake. The turbulence was driven by internal seiching with a period of 18 h. This per ...
