Mg Evaporation Consistency via Plasma
Transient Thermal Modeling (COMSOL Multiphysics)
This project models magnesium evaporation from a tungsten boat under resistive heating using COMSOL. A current sweep (0–90 A) is applied to study temperature profiles, phase change behavior, and evaporation dynamics. The goal is to improve yield uniformity and reduce magnesium loss during plasma-assisted synthesis of nanoparticles.
Core Simulation Features
Joule Heating: resistive current sweep (0–90 A) drives thermal loading in tungsten boat.
Evaporation Model: latent heat removal from Mg surface due to vaporization phase transition.
Radiative Loss: modeled using Stefan–Boltzmann surface radiation to simulate cooling.
IR Validation: thermal camera images aligned with COMSOL temperature field output.
Status: Final convergence tuning + IR overlay validation underway.
Target Completion: Full simulation report + experimental overlay validation by June 24.

Let’s Collaborate
I’m currently exploring advanced cooling and shielding strategies for high-radiation systems — and would love to collaborate with teams working on SMRs, space systems, or thermoelectric materials research.
