Gas microflows can, for example, be observed in microheat exchangers designed for chemical applications or for cooling of electronic components, in fluidic microactuators developed for active flow control purposes, in micronozzles used for the micropropulsion of nano and picosats, in microgas chromatographs, analyzers or separators, in vacuum generators and in Knudsen micropumps, as well as in some organs-on-a-chip, such as artificial lungs. These flows are rarefied due to the small MEMS dimensions, and the rarefaction can be increased by low-pressure conditions. The flows relate to the slip flow, transition or free molecular regimes and can involve monatomic or polyatomic gases and gas mixtures. Hydrodynamics and heat and mass transfer are strongly impacted by rarefaction effects, and temperature-driven microflows offer new opportunities for designing original MEMS for gas pumping or separation. Accordingly, this Special Issue seeks to showcase research papers, short communications, and review articles that focus on novel theoretical and numerical models or data, as well as on new experimental results and technics, for improving knowledge on heat and mass transfer in gas microflows. Papers dealing with the development of original gas MEMS are also welcome. 610 $apreconcentrator 610 $aUV absorption 610 $abearing characteristics 610 $aultraviolet light-emitting diode (UV LED) 610 $aresonant micro-electromechanical-systems (MEMS) 610 $aheat sinks 610 $ameasurement and control 610 $aflow choking 610 $amixing length 610 $agas flows in micro scale 610 $aBTEX 610 $akinetic theory 610 $aPID detector 610 $aethylbenzene and xylene (BTEX) 610 $acomputational fluid dynamics (CFD) 610 $aOpenFOAM 610 $adirect simulation Monte Carlo (DSMC) 610 $athermally induced flow 610 $avacuum micropump 610 $aminiaturization 610 $agaseous rarefaction effects 610 $amodelling 610 $avolatile organic compound (VOC) detection 610 $asupersonic microjets 610 $aslip flow 610 $aNano-Electro-Mechanical Systems (NEMS) 610 $amicro-mirrors 610 $amicro-scale flows 610 $amicrofabrication 610 $aKnudsen pump 610 $amicrofluidic 610 $amicrofluidics 610 $ahollow core waveguides 610 $acapillary tubes 610 $agas mixing 610 $aadvanced measurement technologies 610 $aDSMC 610 $aMicro-Electro-Mechanical Systems (MEMS) 610 $amicrochannels 610 $aminiaturized gas chromatograph 610 $aPitot tube 610 $amulti-stage micromixer 610 $aanalytical solution 610 $apressure drop 610 $amicro-mixer 610 $athermal transpiration 610 $aphotoionization detector 610 $aFE analysis 610 $agas mixtures 610 $aspectrophotometry 610 $aKnudsen layer 610 $apulsed flow 610 $aFanno flow 610 $aintegrated micro sensors 610 $abinary gas mixing 610 $amodified Reynolds equation 610 $ararefied gas flow 610 $ararefied gas flows 610 $abackward facing step 610 $amodular micromixer 610 $afractal surface topography 610 $aunderexpansion 610 $aelectronic cooling 610 $asplitter 610 $acompressibility 610 $aphotolithography 610 $aBenzene 610 $aout-of-plane comb actuation 610 $agas sensors 610 $aaerodynamic effect 610 $afluid damping 610 $atoluene 610 $acontrol mixture composition 700 $aBaldas$b Lucien$4auth$01300028 702 $aColin$b Ste?phane$4auth 906 $aBOOK 912 $a9910367750003321 996 $aGas Flows in Microsystems$93025869 997 $aUNINA
