...Jean-Pierre Franc; Guillaume Boitel; Michel Riondet; Éric Janson; Pierre Ramina; Claude Rebattet Temperature depression within the leading edge cavities on a space inducer is measured in Refrigerant 114 using miniature thermocouples mounted on the rotating blades. Time-averaged values of cavity...

...Jean-Pierre Franc; Guillaume Boitel; Michel Riondet; Éric Janson; Pierre Ramina; Claude Rebattet The thermodynamic effect on a cavitating inducer is investigated from joint experiments in cold water and Refrigerant 114. The analysis is focused on leading edge cavitation and cavitation instabilities...

...Akhil Agarwal; Srinivas Garimella This paper presents a multiple flow-regime model for pressure drop during condensation of refrigerant R134a in horizontal microchannels. Condensation pressure drops measured in two circular and six noncircular channels ranging in hydraulic diameter from 0.42 mm...

...Ling-Xiao Zhao; Chun-Lu Zhang; Liang-Liang Shao; Liang Yang Adiabatic capillary tubes and short tube orifices are widely used as expansive devices in refrigeration, residential air conditioners, and heat pumps. In this paper, a generalized neural network has been developed to predict the mass flow...

... bubble traveling on the suction side of the blade. Cavity shape and temperature distribution predicted by both models are compared. The evolutions of cavity length with the cavitation number for cold water (without thermal effects) and for Refrigerant 114 at two different temperatures is compared...

..., scrolls, check valve, and discharge plenum. Refrigerant-22 is used as the working fluid. The unsteady flows inside and between the gas pockets are characterized by the instantaneous distributions of field quantities and the area- and mass-averaged parameters. Inside the scrolls, the gas pockets change...
