FRICTIONAL PRESSURE DROP DURING CONDENSING FLOW INSIDE MINI/MICRO-CHANNELS: PREDICTIVE TOOLS ASSESSMENT AND DATA TREATMENT
نویسندگان
چکیده
A total of 1210 new condensation friction pressure gradient points (database) is collected from 12 open articles on mini/micro-channels literature. The database covered a wide range thermophysical properties associated with low-GWP refrigerants, physical dimension, mass velocity and vapor quality. comparison the experimental against eleven two-phase flow frictional drop prediction tools carried out. Based that, mini/micro-channel developed by Xu Fang exhibited best ability to capture tendency mean absolute relative deviation (36.59%) for all data. Keywords: Two-phase gradient; Mini/micro-channels; Condensing flow; New refrigerant fluid; Heat transfer; Collect database.

Universal approach to predicting two-phase frictional pressure drop for adiabatic and condensing mini/micro-channel flows
Previous models and correlations for the prediction of pressure drop in adiabatic and condensing mini/ micro-channel flows have been validated for only a few working fluids and relatively narrow ranges of relevant parameters. A universal predictive approach for these flows must be capable of tackling many fluids with drastically different thermophysical properties and very broad ranges of all g...
متن کاملFlow condensation in parallel micro-channels – Part 1: Experimental results and assessment of pressure drop correlations
In this first part of a two-part study, experiments were performed to investigate condensation of FC-72 along parallel, square micro-channels with a hydraulic diameter of 1 mm and a length of 29.9 cm, which were formed in the top surface of a solid copper plate. The condensation was achieved by rejecting heat to a counter flow of water through channels brazed to the underside of the copper plat...
متن کاملTwo-phase frictional pressure gradient of R236ea, R134a and R410A inside multi-port mini-channels
In the present paper the pressure drop characteristics of a 1.4 mm hydraulic diameter multiport minichannel tube during adiabatic two-phase flow of HFC refrigerants are discussed. The tube consists of eleven parallel rectangular cross section channels. Although much experimental research has been devoted to investigate the pressure drop characteristics of R134a inside multiport minichannels in ...
