Spherically symmetric droplet combustion experiments were performed at the NASA Glenn Research Center (GRC) 2.2 second drop tower in Cleveland, OH in an effort to better understand the mechanism leading to sootshell format on. Rapid insertion of a blunt plunger was used to remove the symmetric sootshell that formed during the period of quasi-steady burning. This allowed for the observation of sootshell re-formation. Soot particles were formed near the flame front and migrated towards the droplet to ultimately reside at the sootshell location. These experiments helped to bring about a better understanding of soot transport in microgravity droplet combustion..

Experimental and numerical study of flow and thermal transport in fractured rock Tavakkoli Osgouei, Yashar; Akın, Serhat (Springer Science and Business Media LLC, 2021-01-01) An experimental and numerical study was carried out to investigate matrix-fracture thermal transport in fractured rock. Two different synthetically fractured core plugs were used during the flow-through experiments while core plugs' outer surface was maintained at two different constant temperatures. To investigate the matrix-fracture thermal transport, cold water was injected through the single fracture core plugs at different flow rates. A film type heat flux sensor was used in the fractured core plug to ...
An experimental investigation on performance of annular fins on a horizontal cylinder in free convection heat transfer Yildiz, S; Yüncü, Hafit (Springer Science and Business Media LLC, 2004-02-01) Natural convection heat transfer in annular fin-arrays mounted on a horizontal cylinder was experimentally investigated. An experimental set-up was constructed to investigate heat transfer characteristics of 18 sets of annular fin-arrays mounted on a horizontal cylinder of 24.9-mm diameter in atmospheric conditions. Keeping the fin thickness fixed at 1 mm, fin diameter is varied from 35 mm to 125 mm and fin spacing is varied from 3.6 mm to 31.7 mm. The base-to-ambient temperature difference was also varied ...
Experimental Thermal Performance Characterization of Flat Grooved Heat Pipes Alijani, Hossein; ÇETİN, BARBAROS; Akkus, Yigit; Dursunkaya, Zafer (Informa UK Limited, 2019-06-15) The thermal characterization of aluminum flat grooved heat pipes is performed experimentally for different groove dimensions. Three heat pipes with groove widths of 0.2 mm, 0.4 mm, and 1.5 mm are used in the experiments. The effect of the amount of the working fluid is extensively studied for each groove width. The results reveal that, although all three succeed in dissipating the heat input through the phase change of the working fluid by continuous evaporation and condensation, the effectiveness of the he...
Simulations and Experiments of EMFY-1 Electromagnetic Launcher Ceylan, Doga; Karagoz, Mustafa; Cevik, Yasin; Yildirim, Baran; Polat, Hakan; Keysan, Ozan (Institute of Electrical and Electronics Engineers (IEEE), 2019-07-01) ASELSAN Inc. has been conducting experimental research on electromagnetic launch technologies since 2014. The first prototype, EMFY-1, has 25 mm x 25 mm square bore and 3-m-length rails. In addition, two capacitor-based pulsed-power supplies (PPSs) with 1- and 4-MJ stored energy are built to supply launcher. During the design process of EMFY-1, a 3-D finite element (FE) model has been developed to simulate the electromagnetic and mechanical aspects of the railgun. This paper presents the simulation and expe...
Analysis and modeling of edge fluctuations and transport mechanism in the Maryland Centrifugal Experiment Uzun Kaymak, İlker Ümit; Clary, R.; Ellis, R. F.; Hassam, A. B.; Teodorescu, C. (AIP Publishing, 2008-11-01) The Maryland Centrifugal Experiment [R. F. Ellis , Phys. Plasmas 12, 055704 (2005)] is a mirror machine designed to have a plasma axially confined by supersonic rotation and dominantly interchange stable by the radial shear in the azimuthal velocity. Nevertheless, residual fluctuations still persist. To investigate the presence of such fluctuations, an azimuthal array of 16 magnetic pickup coils at the edge region of the plasma has been employed. A comprehensive analysis of the magnetic fluctuations reveals...
