A numerical study of laminar natural convective heat transfer in air from a pair of equi-temperature horizontal cylinders placed one above the other in a vertical plane was carried out. Prime attention was focused on how heat transfer characteristics of the upper cylinder are affected by center-to-center separation distance between two cylinders (CCD). The study was limited to Rayleigh number ranging from 2 x 10(4) to 2 x 10(5) . The vertical center-to-center separation distance between the cylinders was varied from two to ten cylinder diameters. A finite difference scheme based on the integration of the governing equations over finite cells was used. Temperature profiles around two cylinders, and heat transfer coefficients for each cylinder were obtained. The effect of center-to-center separation distance between the cylinders on heat transfer from the upper cylinder was considered. For assessing the accuracy of the current computational approach the results are compared with the experimental results reported by Sparrow and Niethammer [10].

Effect of Gas Diffusion Layer Characteristics and Addition of Pore-Forming Agents on the Performance of Polymer Electrolyte Membrane Fuel Cells Senguel, Erce; Erkan, Serdar; Eroğlu, İnci; BAÇ, NURCAN (Informa UK Limited, 2009-01-01) The performance of five layer membrane electrode assemblies having different characteristics of gas diffusion layers was determined at 70 degrees C cell temperature and ambient pressure. The maximum power density at 0.6 V was 0.36 W/cm(2) for the membrane electrode assembly prepared with the gas diffusion layer having minimum thickness (SGL BC 30 type). On the other hand, the maximum power density at 0.5 V was 0.44 W/cm(2) for the membrane electrode assembly prepared with SGL BC 34 type gas diffusion layer....
EXPERIMENTAL-STUDY OF UNSTEADY FORCED-CONVECTION IN A DUCT WITH AND WITHOUT ARRAYS OF BLOCK-LIKE ELECTRONIC COMPONENTS LI, W; KAKAC, S; HATAY, FF; OSKAY, R (Springer Science and Business Media LLC, 1993-01-01) An experimental apparatus was designed, built and used to study the behavior of transient forced convection in a rectangular duct with and without barriers due to a sinusoidal heat input at the inlet. to simulate the electric heating and cooling inside the computer. A wide range of Reynolds number (400 less-than-or-equal-to Re less-than-or-equal-to 20,000) and inlet frequencies (0.01 Hz less-than-or-equal-to beta less-than-or-equal-to 0.08 Hz) was covered in this experimental study for both laminar and turb...
DETERMINATION OF MOISTURE DIFFUSIVITY AND BEHAVIOR OF TOMATO CONCENTRATE DROPLETS DURING DRYING IN AIR KARATAS, S; ESIN, A (Informa UK Limited, 1994-01-01) The drying mechanism and diffusion coefficient of water in spherical droplets (1.73 - 2.08 mm diameter) of tomato concentrates were successfully interpreted and modelled by using Fick's law. Solids content of the initial concentrate (5-15% w/w), and drying temperature (60-degrees - 100-degrees-C) were varied but the drying air was kept at constant velocity and humidity.
Effect of thermal neutron irradiation on the elastic constants of tourmaline Özkan, H. (Informa UK Limited, 1987-2) The effect of thermal neutron irradiation due to the B10(n, α)Li7 reaction on the elastic wave velocities and the elastic moduli of tourmaline crystals has been studied. Oriented tourmaline samples have been irradiated with thermal neutrons to 7.6 × 1018n/cm2 and the elastic wave velocities determined by ultrasonic measurements. The elastic wave velocities are not affected by thermal neutron irradiation below 8 × 10l7n/cm2, effects starting to appear at approximately 1 × l018n/cm2 with more important decrea...
Effect of roughness on flow measurements in sloping rectangular channels with free overfall Fırat, Can Ersen; Tiğrek, Şahnaz; Department of Civil Engineering (2004) The characteristics of the subcritical, critical and supercritical flows at the rectangular free overfall were studied experimentally to obtain a relation between the brink depth and the flow rate. A series of experiments were conducted in a tilting flume with wide range of flow rate and two bed roughness in order to find the relationship between the brink depth, normal depth, channel bed slope and bed roughnesses. An equation was proposed to calculate the flow rate if only the brink depth, roughness, and c...
