2012-12-26strong slip acceleration transients can be generated there evenbyapparentlyunfavorable (negative) loads Section 4 3 summarizes important analytical results Section 5 discusses their implications on the properties of postseismic slip and slow earthquakes 2 Model Formulation [7] We consider a fault governed by rate-and-state friction
In this analysis we present a theoretical study to examine the combined effect of both slip velocity and periodic body acceleration on an unsteady generalized non-Newtonian blood flow through a stenosed artery with permeable wall A constant transverse magnetic field is applied on the peristaltic flow of blood treating it as an elastico-viscous electrically conducting and incompressible fluid

2013-3-22The effects of hydrodynamic and thermal slip boundary conditions on the double-diffusive free convective flow of a nanofluid along a semi-infinite flat solid vertical plate are investigated numerically It is assumed that free stream is moving The governing boundary layer equations are non-dimensionalized and transformed into a system of nonlinear coupled similarity equations
Abstract The effect of surface wettability on droplet impact on spherical surfaces is studied with the CLSVOF method When the impact velocity is constant with the increase in the contact angle (CA) the maximum spreading factor and time needed to reach the maximum spreading factor (t max) both decrease the liquid film is more prone to breakup and rebound
2015-3-13Enormous earthquakes repeatedly occur in subduction zones and the slips along megathrusts in particular those propagating to the toe of the forearc wedge generate ruinous tsunamis Quantitative evaluation of slip parameters (i e slip velocity rise time and slip distance) of past slip events at shallow tsunamigenic part of the fault is critical to characterize such earthquakes
The study concentrates on examining the effect of the change in the Knudsen number (Kn) on the velocity profiles magnitude of slip at the wall and skin friction coefficient Assuming that a difference between the two slip models of the order of 10% or less justifies the use of the simple first-order model the transitional Kn numbers have
2014-6-13magnetic field with slip boundary condition numerically and analytically El-Shehawey et al [19]-[22] studied the effect of body acceleration in different situations They studied the effect of MHD flow of blood under body acceleration and the Womersley problem for pulsatile flow of blood through a porous medium The blood flow

(a) Shear stress near the tip of a propagating slip pulse The parameters τ p and τ r are peak and residual shear stresses and σ yx 0 or σ yz 0 is the initial shear stress R is the slip weakening distance L is the length of the pulse [from Rice et al 2005] (b) Contour plot of the maximum Coulomb stress as a function of position around the tip of a slip pulse

2015-6-15This paper presents the study of blood flow through stenosed artery with the effect of external body acceleration and slip velocity Blood has been considered as non-Newtonian Bingham plastic fluid model The non-linear differential equations governing the fluid flow are solved using the perturbation method and Matlab
2012-2-2Rise velocity As seen previously the problem in two-phase flow is to find an appropriate expression for the mixture density Pm' by estimating the liquid holdup HL The liquid holdup or the gas void fraction (1 - HL) depends on the in situ velocity of the gas phase Vg The gas velocity is greater than the mixture velocity Vm because of the
Centripetal acceleration can be calculated by taking the linear velocity squared divided by the radius of the circle the object is traveling along Key Terms acceleration: The amount by which a speed or velocity increases (and so a scalar quantity or a vector quantity) circular motion: Motion in such a way that the path taken is that of a circle
Effect of the velocity slip on the radial velocity in the absence/presence of porous matrix and the presence of the magnetic parameter is presented in Figure 6 for various physical parameters Slip has a significant role on the profile Pick in velocity distribution is noted in the absence of the slip and porosity parameter

Also they claimed that increased Reynolds number would lead to the increases of fluid velocity and wall shear stress Siddiqui et al [12] have modelled the blood as non-Newtonian Bingham plastic fluid model The model was used to study the flow through stenosed artery in the presences of slip velocity and body acceleration

Figs 6a-6c show the effects of velocity slip variable thermal conductivity and viscosity parameters on the dimensionless velocity temperature and nanoparticle volume fraction (nanoparticle concentration) It is found that the fluid velocity is an increasing function of velocity slip parameter (δ) (see Fig 6a) This is perhaps because when
