A Hybrid Discrete Exterior Calculus Discretization and Fourier Transform of the Incompressible Navier-Stokes Equations in 3D
Abdullah Abukhwejah, Pankaj Jagad, Ravi Samtaney +1
The simulation of fluid flow problems, specifically incompressible flows governed by the Navier-Stokes equations (NSE), holds fundamental significance in a range of scientific and…
A hybrid discrete exterior calculus and finite difference method for Boussinesq convection in spherical shells
Bhargav Mantravadi, Pankaj Jagad, Ravi Samtaney
We present a new hybrid discrete exterior calculus (DEC) and finite difference (FD) method to simulate fully three-dimensional Boussinesq convection in spherical shells subject to…
Discrete exterior calculus discretization of two-phase incompressible Navier-Stokes equations with a conservative phase field method
Minmiao Wang, Pankaj Jagad, Anil N. Hirani +1
We present a discrete exterior calculus (DEC) based discretization scheme for incompressible two-phase flows. Our physically-compatible exterior calculus discretization of single p…
Effects of Rotation on Vorticity Dynamics on a Sphere with Discrete Exterior Calculus
Pankaj Jagad, Ravi Samtaney
We investigate incompressible, inviscid vorticity dynamics on a rotating unit sphere using a Discrete Exterior Calculus (DEC) scheme. For a prescribed initial vorticity distributio…
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.…
Flow Past a Circular Cylinder on Curved Surfaces
Pankaj Jagad, Mamdouh S. Mohamed, Ravi Samtaney
We investigate the dynamics of flows past a stationary circular cylinder embedded on spherical and cylindrical surfaces at a fixed Reynolds number of 100. For flows on surfaces, it…
