Two-phase flow patterns in U-bends and their contiguous straight tubes for different orientations, tube and bend diameters

John Richard Thome, Ricardo Lima

In two-phase systems there are many singularities in piping systems, one of which in particular are U-bends (also called 180 degrees return bends or U-tubes) found very often in air conditioning coils, refrigerant systems, etc. Contrary to the literature c ...

Orthotropic active strain models for the numerical simulation of cardiac biomechanics

Alfio Quarteroni, Ricardo Esteban Ruiz Baier, Simone Rossi

An active strain formulation for orthotropic constitutive laws arising in cardiac mechanics modeling is introduced and studied. The passive mechanical properties of the tissue are described by the Holzapfel-Ogden relation. In the active strain formulation, ...

Modelling occupants’ personal characteristics for thermal comfort prediction

Darren Robinson, Frédéric Haldi

Based on results from a field survey campaign conducted in Switzerand, we show that occupants’ variations in clothing choices, which are relatively unconstrained, are best described by the daily mean outdoor temperature and that major clothing adjustments ...

Predictions on heat transport and plasma rotation from global gyrokinetic simulations

Laurent Villard, Trach-Minh Tran, Alberto Bottino, Sébastien Jolliet, Ben McMillan, Paolo Angelino

Flux-driven global gyrokinetic codes are now mature enough to make predictions in terms of turbulence and transport in tokamak plasmas. Some of the recent breakthroughs of three such codes, namely GYSELA, ORB5 and XGC1, are reported and compared wherever a ...

Modelling of drying and cracking initiation in a gallery excavated in shale

Lyesse Laloui, Hervé Péron, John Eichenberger, Simon Salager

Damage induced by desiccation (i.e. drying shrinkage and cracking) is an issue to be investigated in deep geological nuclear waste storage engineering. A dried and cracked zone can form in the underground gallery host shale due to ventilation effects. Incr ...

On the unification of thermal perception and adaptive actions

Darren Robinson, Frédéric Haldi

Occupants exercise adaptive actions in response to discomforting environmental stimuli in an attempt to restore their comfort. These responses to adaptive actions are either ignored (conventional PMV models) or handled in an aggregated way (adaptive therma ...

Development of solar ventilated façade system for building energy retrofit

Christian Roecker, Maria Cristina Munari Probst, Alessia Giovanardi

In the perspective of setting ambitious targets for new buildings energy performance and of introducing new approaches to retrofit existing buildings, the implementation of solar thermal collectors into façade becomes very interesting Several research acti ...

Steerable Miniature Jumping Robot

Dario Floreano, Mirko Kovac, Jean-Christophe Zufferey, Manuel Schlegel

Jumping is used in nature by many small animals to locomote in cluttered environments or in rough terrain. It offers small systems the benefit of overcoming relatively large obstacles at a low energetic cost. In order to be able to perform repetitive jumps ...

Albedo effect on radiative errors in air temperature measurements

Michael Lehning, Marc Parlange, Chad Higgins, Marc-Olivier Boldi

Most standard air temperature measurements are subject to significant errors mainly due to sensor heating by solar radiation, even when the measurement principle is accurate and precise. We present various air temperature measurements together with other m ...
