Transition of fluid flow from orderly (laminar) to chaotic state (turbulent) has been a topic of
intense research over the last century and half. In fact, it is considered one of the unsolved
problem of classical physics, as many eminent scientists including Heisenberg, Kolmogorov, Landau and
many others have tried to solve this problem. In its recent developments, authors at HPCL,
Aerospace Engineering, IIT Kanpur have tried to ascertain whether the turbulent state is a
consequence of determinism or randomness (stochasticity).
The research group at IIT Kanpur have now come out with definitive answers to some of
these questions by looking at a canonical problem of flow past a flat plate. Through their
early theoretical work on Bromwich contour integral method (developed also in IITK since
1990) in explaining formation of spatio-temporal wave front (also published in PRL, 2006)
and recent high accuracy computing methods of following the evolution of this front, they
did manage to recreate final turbulence via deterministic excitation of laminar flow.
So the wait may finally be over for many of the questions raised about turbulence!Also, with
this many branches of physics (and fluid mechanics in particular) will be rejuvenated. This
shows the importance of high accuracy computing's synergy with theoretical fluid mechanics.

•Recent trends in HPC at HPCL, IIT Kanpur, Sep 2009: An account of work done in High Performance Computing Laboratory (HPCL), Department of Aerospace Engineering, I. I. T. Kanpur, in developing high accuracy methods for DNS and LES was displayed in the Workshop on "High Performance Computing in India" in conjunction with "Supercomputing 2009" (SC09), Nov. 14-20, 2009 (USA).
• Issues related to DNS and LES and the topics discussed below, were the central themes of the plenary talk given at the Fifth M.I.T Conference at Boston, June 2009
1. It is often noted that three-time level methods like second order Adam-Bashforth schemes are used for " DNS". Such claims are incorrect - as the following two papers (from J. Sci. Comp.) have shown that the numerical/ spurious mode removes large fraction of initial conditions at higher frequencies:

b) High Accuracy Schemes for DNS and Acoustics

2. The celebrated von Neumann analysis for linear PDEs has been shown to be incorrect, with the help of the model 1D convection equation. See the following short note from J. Computational Physics:
