An analysis is performed to study the influence of nonuniform double slot suction on a steady laminar boundary layer flow over a rotating sphere when fluid properties such as viscosity and Prandtl number are inverse linear functions of temperature. Nonsimilar solutions have been obtained from the starting point of the streamwise co-ordinate to the exact point of separation. The difficulties ari...
During injection, inertial fusion energy (IFE) direct drive targets are subjected to heating from energy exchange with the background gas and radiation from the reactor wall. This thermal loading could cause phase change (vaporization and/or melting) of the deuteriumtritium (DT). In the past, it was assumed that any phase change would result in a violation of the stringent smoothness and symmet...
buckle folds are common traps for hydrocarbon in several contractional provinces. buckle folds form where stratified sequences rest a top salt or some other utterly weak rock as a decollemet zone in units with high competency contrasts by a compressive stress which acted along the length of the rock layers. an important parameter affecting buckle folding of a competent zone above a mobile decol...
The purpose of present problem is to studies of effects of variable viscosity and heat source on unsteady laminar flow of dusty conducting fluid between parallel porous plates through porous medium with temperature dependent viscosity. The fluid is considered as unsteady laminar flow through porous medium and acted upon by a constant pressure gradient and an external uniform magnetic field is a...
To analyse the performance of mushroom-shaped fibrillar adhesive microstructure, its behaviour was studied during different stages of attachment-loading-detachment cycle. Visualizing the evolutions of real contact area of single microfibres, it is shown that the mushroom-shaped geometry of contact elements promotes fast and simple generation of reliable adhesion. The mushroom-shaped geometry se...
Abstract—The high-order symplectic finite-difference time-domain scheme is applied to modeling and simulation of waveguide structures. First, the perfect electric conductor boundary is treated by the image theory. Second, to excite all possible modes, an efficient source excitation method is proposed. Third, the modified perfectly matched layer is extended to its high-order form for absorbing t...
River floods, dammed lake flood discharge, reservoir seawater recession, etc. all cause the water level in front of a slope to drop, which changes original steady-state seepage field soil, leading harmful instability. To study this phenomenon, numerical model was established through theoretical analysis combined with coupling Seep/W and Slope/W modules GeoStudio finite element software, verifie...
The paper presents experimental results from unconfined compression and splitting tensile tests used in combination order to estimate the cohesion intercept of unsaturated soils. Samples different soils form slurry were subjected various suction values using axis translation technique a pressure plate extractor then these samples removed tests. Mohr’ circles for two loading conditions drawn tan...
Loosely packed cohesionless soils may suffer partial or complete liquefaction during seismic loading, causing significant structural damage. The dynamic behavior of liquefiable is widely investigated through element testing under controlled cyclic loading in undrained conditions. In this work, a total 20 stress-controlled triaxial experiments were conducted on saturated specimens clean sand to ...
