Fluid-structure thermal coupling and ablation effects in atmospheric entry

This thesis deals with the modelling of fundamental aspects of the mission engineering, the physics, and the constraints of atmospheric entry of space vehicles. The aim of this work is to formulate a coupled approach for the modelling and the simulation of ...

Radiation-Ablation Coupling for Capsule Reentry Heating via Simulation and Expansion Tube Investigations

Pénélope Leyland, Umar Sheikh, Daniel Potter, Ojas Joshi, Nikhil Banerji, Jérémy Raphaël Mora-Monteros, Valentin Marguet, Elise Joy Fahy

A capsule entering a planetary atmosphere at hypersonic speeds experiences high levels of radiative heating. Furthermore, coupling between the ablation products from the surface of the vehicle and the high temperature gas can have a major effect on the hea ...

Quantification of Carboxylic and Carbonyl Functional Groups in Organic Aerosol Infrared Absorbance Spectra

Satoshi Takahama

Atmospheric aerosols are one of the least understood components of the climate system and incur adverse health effects on susceptible populations. Organic aerosols can make up as much as 80% of atmospheric aerosols (Lim and Turpin

Modelling the effect of size on the aerial dispersal of microorganisms

Edward Mitchell, Isabelle Bey, Symeon Koumoutsaris

Aim We investigate the long-standing question of whether the small size of microbes allows most microbial species to colonize all suitable sites around the globe or whether their ranges are limited by opportunities for dispersal. In this study we use a mod ...

Influence of the moisture content on the shear strength of welded wood-to-wood connections

Yves Weinand, Bernhard Stamm, Benjamin Hahn, Georg Lorenz Rossmair

Friction welding of wood is an innovative process, able to join pieces of wood without additional adhesives. Because of its hygroscopic properties, the wood matrix absorbs humidity at the surface from the surrounding atmosphere. Its moisture content is str ...

A radiative transfer model for an idealized and non-scattering atmosphere and its application for ground-based remote sensing of the troposphere

Marc Schneebeli Zeugin

Inversion of tropospheric profiles from ground-based microwavemeasurements requires a simple and accurate model for calculating the brightness temperatures as received by the radiometer. In the first part, an analytic solution of the radiative transfer equ ...

Effect of mechanical alloying atmosphere on the microstructure and Charpy impact properties of an ODS ferritic steel

Nadine Baluc, Zbigniew Oksiuta

Two types of oxide dispersion strengthened (ODS) ferritic steels, with the composition of Fe-14Cr-2W-0.3Ti-0.3Y(2)O(3) (in weight percent), have been produced by mechanically alloying elemental powders of Fe, Cr, W, and Ti with Y2O3 particles either in arg ...

Nature an architectural approach. The school and why perception matters. A primary school in Zurich West

Aline Dubach

If we assume that architecture is the art of replacing our immediate surroundings, the designed or constructed space has something in common with nature: it assumes the role of something that surrounds us as a whole. Space is something we perceive and sens ...
