dc.descriptionThis paper was presented at the 3rd Micro and Nano Flows Conference (MNF2011), which was held at the Makedonia Palace Hotel, Thessaloniki in Greece. The conference was organised by Brunel University and supported by the Italian Union of Thermofluiddynamics, Aristotle University of Thessaloniki, University of Thessaly, IPEM, the Process Intensification Network, the Institution of Mechanical Engineers, the Heat Transfer Society, HEXAG - the Heat Exchange Action Group, and the Energy Institute.en_US
dc.description.abstractAn important variable in the designing of gas-liquid reactors is the interfacial area available for the conduction of the two phases. Falling film microreactors (FFMR) are devices which can offer extended specific surfaces (up to 20,000m2/m3) and for this reason they are used in many multiphase processes. The aim of this work is to assess the effect of the microchannel width as well as the flow rate and the physical properties of the liquid phase on the geometrical characteristics (i.e. thickness and surface shape) of the liquid film, which were measured using Micro Particle Image Velocimetry (μ-PIV). The experiments were conducted in single microchannels with widths of 1200, 600 and 300μm and for Reynolds numbers between 0.9 and 39.7, while water and aqueous solutions of glycerol and butanol were used as working fluids. It was also verified that a common expression for predicting film thickness in macroscale is not applicable in microscale.en_US
