This article concentrates on the effect of MHD heat mass transfer on the stagnation point nanofluid flow over a stretching or shrinking sheet with homogeneous-heterogeneous reactions. The flow analysis is disclosed in the neighborhood of stagnation point. Features of heat transport are characterized with Newtonian heating. The homogeneous-heterogeneous chemical reaction between the fluid and di...

Laminar-to-turbulent transition in a swept flat-plate boundary layer is caused by the breakdown of crossflow vortex via high-frequency secondary instability and promoted wall-surface roughness freestream turbulence (FST). Although FST characterized its intensity wavelength, it not clear how wavelength affects turbulent transitions interacts with roughness-induced transition. The depends on wind...

In this paper an efficient split-type Finite-Difference (FD) scheme with high modal resolution – most important for the streamwise convection terms that cause wave transport and interaction – is derived for a mixed Fourier-spectral/FD method that is designed for the spatial direct numerical simulation (DNS) of boundary-layer transition and turbulence. Using a relatively simple but thorough and ...

We present a computational study of the solution of the Falkner-Skan equation (a thirdorder boundary value problem arising in boundary-layer theory) using high-order and high-order-compact finite differences schemes. There are a number of previously reported solution approaches that adopt a reduced-order system of equations, and numerical methods such as: shooting, Taylor series, Runge-Kutta an...

The effects of roughness parameters, including height, diameter, and spacing the cylindrical elements, on turbulent transition are investigated in a three-dimensional boundary layer using direct numerical simulation. There two types process, classified as gradual forced. former is caused by linear development crossflow vortices their secondary instability, while latter an immediate breakdown to...

This paper describes the Synapto-dendritic Kernel Adapting Neuron (SKAN), a simple spiking neuron model that performs statistical inference and unsupervised learning of spatiotemporal spike patterns. SKAN is the first proposed neuron model to investigate the effects of dynamic synapto-dendritic kernels and demonstrate their computational power even at the single neuron scale. The rule-set defin...

The family of wake profiles formed from the Falkner–Skan boundary-layer solutions with negative pressure gradient, m, was shown in (Woodley and Peake, 1997) to be inviscidly absolutely unstable. However, due to numerical difficulties, the limit m→ 0 was not considered there, although the results that were found appeared to indicate that the double Blasius profile (m = 0) is absolutely unstable....

The steady two-dimensional stagnation point flow of a non-Newtonian Walters' B' fluid with slip is studied. The fluid impinges on the wall either orthogonally or obliquely. A finite difference technique is employed to obtain solutions. 1. Introduction. Some rheologically complex fluids such as polymer solutions, blood, paints, and certain oils cannot be adequately described by the Navier-Stokes...

The aim of this work is the study of the two dimensional laminar compressible boundary layer ̄ow, with an adverse pressure gradient in the presence of heat and mass transfer. The partial di€erential equations and their boundary conditions, describing the problem under consideration, are transformed using the compressible Falkner±Skan transformation and the numerical solution of the problem is o...
