A new accuracy-preserving parallel algorithm employing compact schemes is presented for direct numerical simulation of the Navier-Stokes equations. Here the connotation of accuracy preservation is having the same level of accuracy obtained by the pro

Two-dimensional (2D) flow inside a lid driven cavity (LDC) is shown to display multi-modal behavior in a consistent manner following the first Hopf bifurcation with varying Reynolds numbers (Re), depending upon the chosen spatial and temporal discret

It has been shown in recent times that transition to turbulence occurs following two- and three-dimensional routes primarily by what is called the spatiotemporal wave front, for the canonical probl...

The investigation on grid sensitivity for the bifurcation problem of the canonical lid-driven cavity (LDC) flow results is reported here with very fine grids. This is motivated by different researchers presenting different first bifurcation critical

A three-dimensional (3D) transition route for zero-pressure-gradient boundary layer over a flat plate is computationally investigated, for impulsive and nonimpulsive startup of harmonic wall excitation. A monochromatic frequency of excitation is chos

Morkovin (Transition to turbulence, ASME FED Publication, USA, vol 114, pp 1–12, 1991, [33]) classified transition to turbulence in to two main types: (i) The classical primary instability route whose onset is marked along with the presence of TS w

DNS of Wall-Bounded Turbulent Flows ISBN: 9789811300370
A general consensus among fluid dynamicists is that flow transition from laminar to turbulent state occurs due to its instability by imposed and/or background omnipresent disturbances (Drazin and Reid, Hydrodynamic stability, Cambridge University Pre

DNS of Wall-Bounded Turbulent Flows ISBN: 9789811300370
This book covers the topic of direct numerical simulation (DNS) of wall-bounded turbulent flow by first principle approach. It is mandatory to track the flow from laminar state to fully developed turbulent state, and which has been solved very recent
