Hydrodynamics of bubble flow through a porous medium with applications to packed bed reactors
Pranay P. Nagrani, Amy M. Marconnet, Ivan C. Christov
Gas-liquid flows through packed bed reactors (PBRs) are challenging to predict due to the tortuous flow paths that fluid interfaces must traverse. Experiments at the International…
Predictions and Measurements of Thermal Conductivity of Ceramic Materials at High Temperature
Zherui Han, Zixin Xiong, William T. Riffe +8
The lattice thermal conductivity () of two ceramic materials, cerium dioxide (CeO) and magnesium oxide (MgO), is computed up to 1500 K using first principles and the phonon…
Data-driven rheological characterization of stress buildup and relaxation in thermal greases
Pranay P. Nagrani, Ritwik V. Kulkarni, Parth U. Kelkar +4
Thermal greases, often used as thermal interface materials, are complex paste-like mixtures composed of a base polymer in which dense metallic (or ceramic) filler particles are dis…
Dynamic Modeling and Control of a Two-Reactor Metal Hydride Energy Storage System
Patrick Krane, Austin L. Nash, Davide Ziviani +3
Metal hydrides have been studied for use in energy storage, hydrogen storage, and air-conditioning (A/C) systems. A common architecture for A/C and energy storage systems is two me…
Two-fluid modeling of heat transfer in flows of dense suspensions
Pranay P. Nagrani, Federico Municchi, Amy M. Marconnet +1
We develop a two-fluid model (TFM) for heat transfer in dense non-Brownian suspensions. Specifically, we propose closure relations for the inter-phase heat transfer coefficient and…
Machine-Learning Assisted Optimization Strategies for Phase Change Materials Embedded within Electronic Packages
Meghavin Bhatasana, Amy Marconnet
Leveraging the latent heat of phase change materials (PCMs) can reduce the peak temperatures and transient variations in temperature in electronic devices. But as the power levels…
