NANOPARTICLES Production of amorphous nanoparticles by supersonic spray-drying with a microfluidic nebulator

Esther Amstad

Amorphous nanoparticles (a-NPs) have physicochemical properties distinctly different from those of the corresponding bulk crystals; for example, their solubility is much higher. However, many materials have a high propensity to crystallize and are difficul ...

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 ...

Characterization of the Flow Generated in an Annular Test Facility

Peter Ott, Dominique Charbonnier, Elia Colombo, Cécile Deslot

Annular cascades are particularly useful to study the three dimensional phenomena encountered in turbomachines. The Non-Rotating Annular Test Facility of the Swiss Federal Institute of Technology in Lausanne (EPFL) consists in a radial-axial inlet nozzle a ...
