Accurate Computational Algorithms For Hyperbolic Conservation Laws
(2010-10-08)The numerics of hyperbolic conservation laws, e.g., the Euler equations of gas dynamics, shallow water equations and MHD equations, is non-trivial due to the convective terms being highly non-linear and equations being ... -
A Comparative Study Of Different Numerical Techniques Used For Solving Incompressible Fluid Flow Problems
(2010-06-03)Past studies (primarily on steady state problems) that have compared the penalty and the velocity-pressure finite element formulations on a variety of problems have concluded that both methods yield solutions of comparable ... -
A Comparative Study Of The Numerical Techniques Used In The Wrinkling Analysis Of Membranes
(2010-07-19)This work is a comparative study of the various numerical techniques used for analyzing membranes. Membrane analysis is complicated by the fact that local instabilities occur in membranes in the form of small waves or ... -
Fine-Scale Structure Of Diurnal Variations Of Indian Monsoon Rainfall : Observational Analysis And Numerical Modeling
(2010-12-31)In the current study, we have presented a systematic analysis of the diurnal cycle of rainfall over the Indian region using satellite observations, and evaluated the ability of the Weather Research and Forecasting Model ... -
Numerical Methods For Solving The Eigenvalue Problem Involved In The Karhunen-Loeve Decomposition
(2014-05-05)In structural analysis and design it is important to consider the effects of uncertainties in loading and material properties in a rational way. Uncertainty in material properties such as heterogeneity in elastic and mass ... -
Numerical Simulations Of Void Growth In Ductile Single Crystals
(2010-09-03)The failure mechanism in ductile materials involves void nucleation, their growth and subsequent coalescence to form the fracture surface. The voids are generated due to fracture or debonding of second phase particles or ... -

(2010-07-23)The problem of low Mach number (non-Boussin´esq) conjugate laminar natural convection combined with surface radiation in a vertical annulus with a centrally located vertical heat generating rod is studied numerically, ... -
Optimal Control Of Numerical Dissipation In Modified KFVS (m-KFVS) Using Discrete Adjoint Method
(2010-06-04)The kinetic schemes, also known as Boltzmann schemes are based on the moment-method-strategy, where an upwind scheme is first developed at the Boltzmann level and after taking suitable moments we arrive at an upwind scheme ... -
Stability Of Double-Diffusive Finger Convection In A Non-Linear Time Varying Background State
(2010-09-06)Convection set up in a fluid due to the presence of two components of differing diffusivities is known as double diffusive convection. Double diffusive convection is observed in nature, in oceans, in the formation of certain ... -
Weighted Least Squares Kinetic Upwind Method Using Eigendirections (WLSKUM-ED)
(2009-06-24)Least Squares Kinetic Upwind Method (LSKUM), a grid free method based on kinetic schemes has been gaining popularity over the conventional CFD methods for computation of inviscid and viscous compressible flows past complex ...
