Preventing mass loss in the standard level set method: New insights from variational analyses
Kaustubh Khedkar, Amirreza Charchi Mamaghani, Pieter Ghysels +2
For decades, the computational multiphase flow community has grappled with mass loss in the level set method. Numerous solutions have been proposed, from fixing the reinitializatio…
An effective preconditioning strategy for volume penalized incompressible/low Mach multiphase flow solvers
Ramakrishnan Thirumalaisamy, Kaustubh Khedkar, Pieter Ghysels +1
The volume penalization (VP) or the Brinkman penalization (BP) method is a diffuse interface method for simulating multiphase fluid-structure interaction (FSI) problems in ocean en…
A model predictive control (MPC)-integrated multiphase immersed boundary (IB) framework for simulating wave energy converters (WECs)
Kaustubh Khedkar, Amneet Pal Singh Bhalla
In this work, we present a novel MPC-integrated multiphase IB framework that can compute the optimal energy-maximizing control force on-the-fly by dynamically interacting with a hi…
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…
