Data is presented verifying the inertness of pore water pressures in stiff clays to stress changes as Skempton's pore pressure coefficient B drops below about 0.2. In such cases, a total stress analysis based on a direct measurement of strength through undrained tests, more easily applicable on a larger area, is shown to give more reasonable values of factor of safety for the short term stability of slopes in fissured and/or stony clays than effective stress analyses based on small specimens.

Heat transfer enhancement by silver nanowire suspensions in microchannel heat sinks SIMSEK, Eylul; Coskun, Sahin; OKUTUCU-OZYURT, Tuba; Ünalan, Hüsnü Emrah (2018-01-01) Convection heat transfer and pressure drop characteristics of water based silver nanowire suspensions flowing through CMOS compatible monolithic microchannel heat sinks are investigated experimentally. Three different rectangular channels of 200 mu m x 50 mu m, 100 mu m x 50 mu m and 70 mu m x 50 mu m cross sectional area are used during the experiments. The stability of the silver nanofluids is established by the added polyvinylpyrrolidone (PVP) as the surfactant. To investigate the potential heat transfer...
Simulation of laminar microchannel flows with realistic 3D surface roughness Akbaş, Batuhan; Sert, Cüneyt; Department of Mechanical Engineering (2019) Effects of flow development and surface roughness on the pressure drop characteristics of laminar liquid flowsinside microchannels are investigated numerically using OpenFOAM. Channels with square cross section of 500 μm×500 μmand length of 80 mm are studied. Top surface of the channels are artificially roughened using thespatial frequency methodto create 8 different roughness profiles. Scaling the relative roughness ({u1D700}) values of each profile to three different values (1.0, 2.5and5.0 %),a total of 2...
Lateral heating effects on the PVT growth process of Hg2Cl2 crystals Coskun, AU; Arinc, F; Yener, Y (IOP Publishing, 2003-03-01) Effects of lateral heating on flow profiles and growth rates during the growth of mercurous chloride crystals by the physical-vapour-transport process in vertical ampoules are investigated by a two-dimensional model. The growth conditions of an experimental study available in the open literature are simulated. Lateral thermal boundary condition is modelled by a spatially sinusoidal heat flux. The results of the present computations are in agreement with the earlier experimental results and indicate that an ...
Finite element method solution of electrically driven magnetohydrodynamic flow Nesliturk, AI; Tezer, Münevver (Elsevier BV, 2006-08-01) The magnetohydrodynamic (MHD) flow in a rectangular duct is investigated for the case when the flow is driven by the current produced by electrodes, placed one in each of the walls of the duct where the applied magnetic field is perpendicular, The flow is steady, laminar and the fluid is incompressible, viscous and electrically conducting. A stabilized finite element with the residual-free bubble (RFB) functions is used for solving the governing equations. The finite element method employing the RFB functio...
Effects of compaction parameters on heavy metal mass transport in Ankara clay liner: Experimental approach Çamur, Mehmet Zeki; Yazıcıgil, Hasan (2007-01-01) Mass transports of Cl, Cd, Cr, Cu, Fe, K, Mn, Ni, Pb and Zn ions through the Ankara clay liner prepared under two different compaction were studied experimentally on the bases of sorption and hydrodynamic dispersion processes. According to geotechnical tests, the Ankara clay material is highly plastic, inorganic clay having a liquid limit of 73, a plastic limit of 29 and a plasticity index of 44. Optimum compaction of the material requires 32% water content and 1.413 g/cm(3) dry density. Two materials, prep...
