This book was released on 2015 with total page 106 pages. Available in PDF, EPUB and Kindle. Book excerpt: An experimental setup was developed to study the region of subcooled flow boiling. Multiple studies were carried out to investigate the effects of liquid velocity, pressure, and temperature on the boiling heat transfer of subcooled fluid flowing through a heated annular channel. Water was used as the working fluid and principle of Ohmic heating was used to raise water temperature. The system pressure, heat flux, & mass flux ranged from 101 to 912 kPa, 19 to 155 kW/m2, and 83 to 332 kg/m2-s, respectively. This report contains boiling curves, heat transfer coefficients of various studies and a description of the experimental setup.

This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: A series of experimental work to investigate the subcooled boiling flow in a vertical square upward flow channel is described. As experimental methods, high-speed photography and infrared (IR) thermometry were employed simultaneously. The research scope explored includes (i) measurement issues of fundamental bubble parameters through visualization, (ii) experimental methodology to achieve both enhanced two-phase flow visualization and accurate wall temperature measurement, and (iii) measurement of diverse aspects of bubble dynamics as well as wall heat transfer by applying the verified experimental approach. Before producing the actual data, substantial effort was first made to identify the critical measurement issues of fundamental bubble parameters in a forced convective boiling system. Those issues have never been explicitly addressed in previous studies despite the possibly critical impacts on the experimental results. Thus, a series of systematic experimental investigations was performed to uncover those issues and to verify the errors created by not addressing them, based on which more suitable ways of observing and characterizing such parameters through experiments were discussed. Then, an experimental strategy to achieve high-fidelity optical measurements using both high-speed photography and IR thermometry was established. To attain the goal, the important issues such as test section design, IR thermal imaging issues, visualization strategy, wall temperature tracking method, and experimental validations were extensively addressed. Also, the feasibility of current experimental approach was demonstrated through the subcooled flow boiling experiment. Finally, by employing the experimental strategy established, an experimental investigation of the subcooled boiling flow was conducted. The experiment was performed in a vertical square upward flow channel using refrigerant NovecTM 7000, in which a single nucleation site was purposely activated for a fundamental study of subcooled flow boiling process. The various aspects of bubble behavior under different subcooled flow boiling conditions were examined using both micro- and macroscopic views of high-speed cameras while measuring the wall temperature/heat flux with IR thermometry. Additionally, based on the measurements of various bubble parameters as well as wall heat transfer, relevant relations among those parameters and the underlying mechanisms were intensively discussed.

Book excerpt: Experimental heat-transfer data were obtained for the forced-convection boiling of trichlorotrifluoroethane (R-113 or Freon-113) in a vertical annular test annular test section. The 97 data points obtained covered heat transfer by forced convection, local boiling, and fully-developed boiling. Correlating methods were obtained which accurately predicted the heat flux as a function of wall superheat (boiling curve) over the range of parameters studied.

Available in PDF, EPUB and Kindle. Book excerpt: Two-phase flow heat exchangers are vital components of systems for power generation, chemical processing, and thermal environment control. The art and science of the design of such heat exchangers have advanced considerably in recent years. This is due to better understanding of the fundamentals of two-phase flow and heat transfer in simple geometries, greater appreciation of these processes in complex goemetries, and enhanced predictive capability through use of complex computer codes. The subject is clearly of great fundamental and practical importance. The NATO ASIan Thermal-Hydraulic Fundamentals and Design of Two-Phase Flow Heat Exchangers was held in Povoa de Varzim (near Porto), Portugal, July 6-17, 1987. participating in the organization of" the ASI were the Department of Mechanical Engineering and the Clean Energy Research Institute, University of Miami; Universidade do Porto; and the Department of Mechanical Engineering, Aeronautical Eng ineer ing, and Mechanics, Rensselaer Polytechnic Institute. The ASI was arranged primarily as a high-level teaching activity by experts representing both academic and industrial viewpoints. The program included the presentation of invited lectures, a limited number of related technical papers and discussion sessions.
