... be used without requiring a denser mesh [ 15 ]. A 10 s transient heat transfer analysis step was completed. The thermal resistance at the disk/pad interface is not only dependent on the ITL thermal resistance but also on the contact pressure at the interface. With increased contact pressure, the real...

...Hee Joon Lee; Dong Yao Liu; Y. Alyousef; Shi-chune Yao Existing databases and correlations in literature on the microchannel pressure drop and heat transfer are reviewed in this paper. From this review, it is found that none of the existing correlations can cover the wide ranges of working fluids...

...André Burdet; Reza S. Abhari The pulsation of film cooling jets in turbines is driven by the near hole pressure fluctuation caused by the deterministic interaction of stator/rotor blade rows. Jet pulsation is characterized by the coolant near hole reduced frequency Ω c and the pulsation amplitude...

...S. N. Rogak; D. Faraji The constant pressure heat capacity and forced convection heat transfer coefficient of water/oxygen mixtures were measured in a horizontal, smooth, electrically-heated tube. For the supercritical pressure (25 MPa) considered, flow rates (0.76–2.04 kg/min), heat fluxes (21–290...

...Y. Feng; J. Seyed-Yagoobi The mechanism of heat transfer enhancement and pressure drop penalty in the presence of a radial electric field for the two-phase (liquid/vapor) annular flow is presented. The turbulence spectral theory shows that the radial electric field fluctuation changes the turbulent...

...Li Yong and; K. Sumathy Quasi-local absorption heat transfer coefficients and pressure drop inside a horizontal tube absorber have been investigated experimentally, with R-22/DMA as the working pair. The absorber is a counterflow coaxial tube-in-tube heat-exchanger with the working fluid flowing...

...S. K. Saha; P. Langille Heat transfer and pressure drop characteristics in a circular tube fitted with full-length strip, short-length strip, and regularly spaced strip elements connected by thin circular rods have been investigated experimentally. The strips have been rectangular, square...

... component of velocity is compared to the local heat transfer, shear stress and pressure gradient. The results suggest that intermittently grooved passages may offer even higher heat transfer for a given pumping power than the levels observed in fully grooved passages. For Re = 1200 , f P...

...J.-J. Hwang, Professor, Mem. ASME; B.-Y. Chang, Graduate Student Experiments are conducted to study the heat transfer and pressure drop characteristics in a triangular duct cooled by an array of tangential jets, simulating the leading-edge cooling circuit of a turbine blade. Coolant ejected from...

...S.-S. Hsieh, Sun Yat-Sen Professor of Mechanical Engineering, Dean of Engineering, Fellow ASME; I.-W. Huang, Graduate Student, Heat transfer and pressure drop characteristics of water flow in horizontal tubes with/without longitudinal inserts used as a heat exchanger tubing was experimentally...
