A model for frictional pressure drop during vapour-liquid flow in minichannels [Elektronski vir]Cavallini, Alberto ...Present authors have measured pressure drops (Cavalliniet al 2004)during adiabatic flow of R134a,R4l0A and R236ea inside a flat multiport mini-channel tube with a 1.4 mm hydraulic diameter. The ... experimental frictional press ure gradients have been compared against cOrrelations available in the literature and no correlationwas able to predict the gradients in all the experimental conditions. The present paper suggests a model for the frictional pressure gradient valid for adiabatic flow or for flow during condensation inside horizontal mininichannels of halogenated refrigerants. The proposed procedure takes into account the effect of the entrainment rate of droplets from the liquid film. The model is applied to the annular, annular-mist flow. Comparisons between present authors' data and predicted values show the satisfactory behavior of the new model. The model is also able to predict experimental frictional pressure gradients measured by (Coleman 2000), (Zhang 1998), (Hirofurni and Webb 1995), (Webb and Ermis 2001). The model can be extended to interrnittent flow in rninichannels and it is also applied with success to horizontal macro tubes.Type of material - conference contributionPublish date - 2005Language - englishCOBISS.SI-ID - 29249541
