A consistent, volume preserving, and adaptive mesh refinement-based framework for modeling non-isothermal gas-liquid-solid flows with phase change
Ramakrishnan Thirumalaisamy, Amneet Pal Singh Bhalla
This work expands on our recently introduced low Mach enthalpy method [1] for simulating the melting and solidification of a phase change material (PCM) alongside (or without) an a…
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 low Mach enthalpy method to model non-isothermal gas-liquid-solid flows with melting and solidification
Ramakrishnan Thirumalaisamy, Amneet Pal Singh Bhalla
Modeling phase change problems numerically is vital for understanding many natural (e.g., ice formation, steam generation) and engineering processes (e.g., casting, welding, additi…
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…
