Battery systems · vehicle cooling · e-powertrain thermal management · 1D system simulation · 3D CFD/CHT · validation · engineering automation
I am an automotive thermal-simulation engineer with 9+ years of experience spanning vehicle cooling, battery thermal management, electro-thermal heat generation, powertrain cooling and CFD. I use 1D system models to make architecture, controls and duty-cycle decisions, and 3D CFD/CHT to resolve flow distribution, interfaces and component hotspots. My work is grounded in energy balance, test correlation, engineering judgement and reusable automation.
AI and scientific ML are enabling tools in my workflow—used to accelerate knowledge retrieval, post-processing and surrogate modelling—not a substitute for physics and validation.
These are three focused views of one engineering foundation. Select the portfolio that matches the problem you are solving.
| Portfolio | Typical industrial problems | 1D / 3D activity |
|---|---|---|
| Electro-thermal simulation | Busbars, connectors, cables, battery interconnects, temperature rise and hotspots | Thermal networks and loss/ampacity studies / Joule-heating, CHT and cooling-path analysis |
| Battery & vehicle cooling | Battery packs, e-powertrain, coolant loops, radiator–chiller–HVAC interaction, thermal limits | Cooling architecture, controls and drive/charge cycles / pack, cold-plate and component CFD/CHT |
| Battery systems & performance | Cell-to-pack performance, SOC–temperature interaction, safety, range and thermal control | Reduced-order battery/thermal models and system integration / local thermal propagation and heat-path studies |

Clarify the engineering decision → establish energy and heat-transfer physics → select 1D or 3D fidelity → correlate or verify → quantify limits → communicate the design implication.
