Piezoelectric flexing and output voltage of a microchannel heat engine
… a piezoelectric membrane and fluid motion in a microchannel heat engine. A new slug flow model is developed for droplet motion in a circular cross-section channel. The model includes friction, pressure, viscous and thermocapillary forces on the droplet. This thesis examines the concept of a …

Fluid transport and entropy production in electrochemical and microchannel droplet flows
… of producing electrical energy from waste heat produced by industrial or other sources. The thermocapillary motion of fluid droplet in a closed rectangular microchannel is used to generate electrical energy from waste heat in a piezoelectric membrane by inducing mechanical deformation as a …

Enhancing the performance of a self-oscillating fluidic heat engine (SOFHE) through thermodynamic cycle and phase change characterization
… dont la puissance requise est de l'ordre de 10s microwatt. Nous avons également étudié l'effet de la température de fonctionnement de la source de chaleur et de deux paramètres de conception, notamment la longueur de la fibre de mèche et la longueur du bouchon liquide, sur la puissance de la …
