Computational investigation and parametrization of the pumping effect in temperature-driven flows through long tapered channels
Giorgos Tatsios,G. Lopez Quesada,G. Lopez Quesada,Marcos Rojas-Cárdenas,Lucien Baldas,Stéphane Colin,Dimitris Valougeorgis +6 more
TL;DR: In this article, the authors investigated the diode effect of temperature-driven rarefied gas flow and the associated pumping effects through long channels with linearly diverging or converging cross sections.

A one-dimensional model for compressible fluid flows through deformable microchannels
Aryan Mehboudi,Junghoon Yeom +1 more
TL;DR: In this paper, a coupled fluid-solid-mechanics model for the prediction of the characteristic behavior of compressible fluid flows through deformable micro-channels is proposed.
Journal ArticleDOI
Regulation of anti-Fourier heat transfer for non-equilibrium gas flows through micro/nanochannels
TL;DR: In this paper, the authors use the direct simulation Monte Carlo (DSMC) to elaborate on the heat transfer patterns in the pressure-driven rarefied flow through micro/nanochannels.

Thermally driven pumps and diodes in multistage assemblies consisting of microchannels with converging, diverging and uniform rectangular cross sections
Guillermo López Quesada,Guillermo López Quesada,Giorgos Tatsios,Dimitris Valougeorgis,Marcos Rojas-Cárdenas,Lucien Baldas,Christine Barrot,Stéphane Colin +7 more
TL;DR: In this article, the authors investigated thermally transpiration pumping in multistage assemblies, where each stage is formed by combining in series-long microchannels with (a) uniform-uniform (uni-uni), (b) converging-, converging-and diverging-channel cross sections, (c) diverging and diverging diverging channels, and (d) convergent-diverging channels.
Journal ArticleDOI
A physical explanation of the gas flow diode effect
TL;DR: In this article, it was shown that the diode effect depends on the proportion of inclined walls to the overall channel inner surface, and the inclination of the wall itself determines the strength of the effect.

Heat Transfer and Fluid Flow in Minichannels and Microchannels
TL;DR: In this paper, the authors focus on flow through passages with hydraulic diameters from about 1μm to 3 mm, covering the range of microchannels and minichannels, and the challenge is to understand and quantify how utilizing microscale passages alters fluid flow patterns and the resulting, momentum, heat, and mass transfer processes to maximize device performance while minimizing cost, size, and energy requirements.
Journal ArticleDOI
Gaseous slip flow in long microchannels
TL;DR: In this paper, an analytic and experimental investigation into gaseous flow with slight rarefaction through long microchannels is undertaken, and the effect of slip upon the pressure distribution is derived, and it is obtained that this slip velocity leads directly to a wall normal migration of mass.

Equilibrium and transport properties of the noble gases and their mixtures at low density
TL;DR: In this article, a set of easy-to-program expressions for the calculation of the thermodynamic and transport properties of the five noble gases (He, Ne, Ar, Kr, Xe) and of the 26 binary and multicomponent mixtures that can be formed with them are presented.

A valve-less planar fluid pump with two pump chambers
TL;DR: A new planar fluid pump based on the valve-less diffuser/nozzle pump principle is presented, which shows pump flows and pump pressures which are more than twice as high as those of the in-phase oscillation mode.

Mass flow and tangential momentum accommodation in silicon micromachined channels
TL;DR: In this paper, the tangential momentum accommodation coefficient (TMAC) for several gases in contact with single-crystal silicon was found to be less than unity, ranging from 0.75 to 0.85.
