Abstract A combined experimental and numerical study on the laminar-to-turbulent transition in microchannels using gas flow is presented. The effects of two geometric parameters, namely aspect ratio (height to width) of microchannels and inlet manifo

Molecular tagging velocimetry (MTV) is an optic experimental technique widely employed for measuring the velocity field in fluid flows. The measuring principle is based on the tracking of molecules able to emit light in response to a laser excitation

Numerical and experimental analysis of flows generated by temperature fields in rarefied gas : application to the design of Knudsen micropumps

Autor: Chen, Jie

Cette thèse présente une étude numérique et expérimentale d’écoulements gazeux raréfiés confinés, induits par gradients thermiques. L’écoulement d’un gaz raréfié peut en effet être généré en appliquant uniquement un gradient tan
