A Primitive Variable Discrete Exterior Calculus Discretization of Incompressible Navier-Stokes Equations over Surface Simplicial Meshes
Pankaj Jagad, Abdullah Abukhwejah, Mamdouh Mohamed +1
A conservative primitive variable discrete exterior calculus (DEC) discretization of the Navier-Stokes equations is performed. An existing DEC method (Mohamed, M. S., Hirani, A. N.…
Revisiting Reynolds and Nusselt numbers in turbulent thermal convection
Shashwat Bhattacharya, Mahendra K. Verma, Ravi Samtaney
In this paper, we extend Grossmann and Lohse's (GL) model [Phys. Rev. Lett. {\bf 86}, 3316 (2001)] for the predictions of Reynolds number (Re) and Nusselt number (Nu) in turbulent…
Enstrophy transfers in helical turbulence
Shubhadeep Sadhukhan, Roshan Samuel, Franck Plunian +3
In this paper we study the enstrophy transers in helical turbulence using direct numerical simulation. We observe that the helicity injection does not have significant effects on t…
Richtmyer-Meshkov Instability of an Imploding Flow with a Two-Fluid Plasma Model
Y. Li, R. Samtaney, D. Bond +1
The two-fluid (ions and electrons) plasma Richtmyer-Meshkov instability of a cylindrical light/heavy density interface is numerically investigated without an initial magnetic field…
How massive are the superfluid cores in the Crab and Vela pulsars and why their glitch-events are accompanied with under and overshootings?
A. A. Hujeirat, R. Samtaney
The Crab and Vela are well-studied glitching pulsars and the data obtained sofar should enable us to test the reliability of models of their internal structures. Very recently it w…
The generation and sustenance of electric fields in sandstorms
Mustafa Mutiur Rahman, Wan Cheng, Ravi Samtaney
Sandstorms are frequently accompanied by the generation of intense electric fields and lightning. In a very narrow region close to the ground level, sand particles undergo a charge…
