Nithin S. Panicker

Staff Researcher/physics-based modeling and simulation

Dr. Nithin Panicker is a staff member in the Nuclear Systems Performance and Integration group at Oak Ridge National Laboratory (ORNL). He specializes in developing and applying physics-based computational models, ranging from zero-dimensional (0D) and one-dimensional (1D) system and component models to high-fidelity three-dimensional (3D) computational fluid dynamics (CFD) simulations. His expertise encompasses multiphase transport (gas/particle, gas/liquid) fluid flow, heat and mass transfer and coupled multiphysics processes (electrochemical, electromagnetic wave interaction) in energy and manufacturing applications. His work connects system-level performance and transient behavior with detailed spatial resolution of transport phenomena (multi-scale) to support engineering design, optimization, and scale-up.

At ORNL, Dr. Panicker leads modeling and simulation projects supported by the U.S. Department of Energy’s High-Performance Computing for Energy Innovation program, Office of Critical Minerals and Energy Innovation and Office of Nuclear Energy. He collaborates with industry partners including Alcoa USA, EPRI, Spar Systems, CCAM, and Solid Power to address complex engineering challenges

He is currently working on applying modeling and simulation techniques in the following application areas to improve Energy, cost and manufacturing efficiency:

1. Nuclear Canisters disposal in geological repositories

2. Fuel cells and electrochemical material extraction

3. High power electromagnetic wave drilling and rock/mineral interaction

4. Data center waste heat recovery

He is also develops modeling and simulation tools flow, mass transfer and thermal problems in OpenFOAM for a variety of industrial applications
