Ice-stream dynamics are strongly controlled by processes taking place at the ice/bed interface where subglacial water both lubricates the base and saturates any existing, underlying sediment. Large parts of the former Eurasian ice sheet were underlain by thick sequences of soft, marine sediments and many areas are imprinted with geomorphological features indicative of fast flow and wet basal co...

The influence of swirl on the shape of the Burke-Schumann reaction sheet in a straight cylindrical pipe is investigated by asymptotic and numerical means. Attention is confined to swirl levels that are near the critical value at which vortex breakdown occurs. A high Reynolds number, laminar, isothermal, low Mach number reacting flow is considered. An asymptotic analysis is developed to study th...

As the vortical disturbances of a shrouded jet pass the sharp edge of the shroud exit some of the energy is scattered into acoustic waves. Scattering into upstreampropagating acoustic modes is a potential mechanism for closing the resonance loop in the ‘howling’ resonances that have been observed in various shrouded jet configurations over the years. A model is developed for this interaction at...

BACKGROUND Intensive care unit is a center to provide comprehensive care for critically ill patients whose condition can be improved by receiving specialized care. The importance of accurate and rapid monitoring of patients at this precise moment is in recording patient data and its comparison with previous data. Monitoring the patient by either devices or direct examination of the nurses requi...

The West Antarctic Ice Sheet (WAIS) is the only remaining marine ice sheet from the last glacial period. The bed is primarily below sea level and slopes down from the coast to the interior. It has been hypothesized that the ice sheet may be susceptible to run-away grounding line retreat [Weertman, 1974] leading to rapid disintegration and sea level rise. Were the WAIS to completely melt, the wa...

the problem of steady magnetohydrodynamic boundary layer flow of an electrically conducting nanofluid due to an exponentially permeable stretching sheet with heat source/sink in presence of thermal radiation is numerically investigated. the effect of transverse brownian motion and thermophoresis on heat transfer and nano particle volume fraction considered. the governing partial differential eq...

in this study a nonlinear asymmetric instability analysis carried out to study primary atomization of annular liquid sheets emanating from the prefilming airblast atomizer using a perturbation method and potential flow assumption. in this direction, firstly governing equations derived according to potential flow assumption and conservation equations while dynamic and static boundary condition a...

In this paper, an analytical model based on Modified Slab Method is presented for rolling of clad sheet or double-layers in which the two layers are bounded prior to rolling. This model considers the general case of asymmetrical rolling due to unequal &#10surface speed, different contact friction, roll diameters, flow stress, and thickness ratios of the two layers. Using this model, rolling par...

many research studies have been performed on forced convection (active) solar dryers for fruit and vegetables. a short survey of these showed that applying the forced convection solar dryer not only significantly reduced the drying time but also resulted in many improvements in the quality of the dried products. active indirect and mixed-mode thin layer solar drying experiments were conducted o...
