This book was released on 2017-12-27 with total page 452 pages. Available in PDF, EPUB and Kindle. Book excerpt: Flow boiling heat transfer, pressure drop and flow pattern of CO?-POE oil mixtures were experimentally investigated in smooth and micro-fin tubes. The POE oil used features full miscibility in the range of operation investigated. The experimental data was evaluated based on mixture properties, used to evaluate and improve established predictive methods. The knowledge obtained contributes to understanding the influence of oil, which is essential for achieving an efficient evaporator design.

This book was released on 2017-10-28 with total page 80 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Horizontal Convective Condensation of Alternative Refrigerants Within a Micro-Fin Tube As shown in Fig. 3, six refrigerant pressure taps along the test section allowed the measurement of the upstream absolute pressure and five pressure drops along the test section. Two sets of two water pressure taps were used to measure the water pressure drop along each tube. Also, a sheathed thermocouple measured the refrigerant temperature at each end of the two refrigerant tubes, with the junction of each centered radially. Only the thermocouple at the inlet of the first tube was used in the calculations. Theentire test section was wrapped with 5 cm of foam insulation to minimize heat transfer between the water and the ambient.

Download or read book Modeling of Evaporation and Condensation Pressure drop in Micro fin Tubes written by Meng-Onn Tan and published by . This book was released on 2002 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Three existing pressure-drop models are validated and analyzed with experimental data compiled from the research database. From the analysis, it was found that the pressure-drop prediction results from the models are not very accurate and not consistent with all experimental datasets. A new pressure-drop model was consequently created based on the findings from the study, and experimental data from the database were used to validate the model to produce more accurate and consistent predictions. The new pressure-drop model was tested on experimental datasets that were in the database and also with experimental datasets that were not in the database. Good and consistent results were achieved, and the new model proved capable of predicting pressure drops for different pure refrigerants and refrigerant mixtures flowing inside different configurations of micro-fin tubes for both condensation and evaporation.

This book was released on 2011-03 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: The purpose of this work was to study the condensation heat transfer and pressure drop characteristics ofHFC-134a in a micro-fined tube with an 18 degree helix angle and to compare them to those in a smooth tube for various operating conditions.The experimental test facility is designed, developed and is used to determine the condensation HTC and pressure drop in smooth and micro-fin tubes for various HFC refrigerants namely HFC-134a, R-404A, R-407C, R-507A. The experimentation covers wide range of operating parameters such as mass flux and condensing temperatures. The instrumentations used for measurements are calibrated from recognized calibration centres. The hermetically sealed compressor is used for circulating refrigerant; effect of oil present in the refrigerant during condensation is also taken into account. The condensation of HFC-134a and R-404A in smooth and micro-fin tubes are measured and obtained the values of condensation HTCs and pressure drops for different mass flux and condensing temperatures
