Critique on "Volume penalization for inhomogeneous Neumann boundary conditions modeling scalar flux in complicated geometry"
Ramakrishnan Thirumalaisamy, Nishant Nangia, Amneet Pal Singh Bhalla
In this letter, we provide counter-examples to demonstrate that it is possible to retain second-order accuracy using Sakurai et al.'s method, even when different flux boundary cond…
The inertial sea wave energy converter (ISWEC) technology: device-physics, multiphase modeling and simulations
Kaustubh Khedkar, Nishant Nangia, Ramakrishnan Thirumalaisamy +1
In this paper we investigate the dynamics of the inertial wave energy converter (ISWEC) device using fully-resolved computational fluid dynamics (CFD) simulations. Originally proto…
Simulating water-entry/exit problems using Eulerian-Lagrangian and fully-Eulerian fictitious domain methods within the open-source IBAMR library
Amneet Pal Singh Bhalla, Nishant Nangia, Panagiotis Dafnakis +2
In this paper we employ two implementations of the fictitious domain (FD) method to simulate water-entry and water-exit problems and demonstrate their ability to simulate practical…
A DLM immersed boundary method based wave-structure interaction solver for high density ratio multiphase flows
Nishant Nangia, Neelesh A. Patankar, Amneet Pal Singh Bhalla
We present a robust immersed boundary (IB) method for high density ratio multiphase flows that is capable of modeling complex wave-structure interaction (WSI) problems arising in m…
A robust incompressible Navier-Stokes solver for high density ratio multiphase flows
Nishant Nangia, Boyce E. Griffith, Neelesh A. Patankar +1
This paper presents a robust, adaptive numerical scheme for simulating high density ratio and high shear multiphase flows on locally refined Cartesian grids that adapt to the evolv…
A moving control volume approach to computing hydrodynamic forces and torques on immersed bodies
Nishant Nangia, Hans Johansen, Neelesh A. Patankar +1
We present a moving control volume (CV) approach to computing hydrodynamic forces and torques on complex geometries. The method requires surface and volumetric integrals over a sim…
