Why this validation matters
Evaluate whether a proposed coolant geometry and flow boundary condition control maximum cell temperature and spatial nonuniformity under high-rate loading.
Several different numerical or control assumptions can produce visually plausible plots. The validation must establish that the observed trend comes from the intended physical mechanism rather than mesh, solver, controller or boundary-condition artifacts.
First-pass physical and numerical checks
- Separate reversible and irreversible heat where the source model allows.
- Do not assume 3C automatically produces a fixed uniform heating power at every SOC.
- Check near-wall mesh quality and coolant Reynolds regime before comparing flow-rate cases.
- Measurement cross-check: Maximum and mean cell temperature versus time.
- Measurement cross-check: Temperature spread across cells and along the coolant flow path.
Challenge the model under changed inputs
- Case 1: natural-convection module. Establish a reference case, change one physical assumption and compare the same metrics across runs.
- Case 2: baseline liquid-cooling channel. Establish a reference case, change one physical assumption and compare the same metrics across runs.
- Case 3: modified channel flow/contact design. Establish a reference case, change one physical assumption and compare the same metrics across runs.
Quantities to retain for audit
- Archive maximum and mean cell temperature versus time with units, time window, data export format and configuration identifier.
- Archive temperature spread across cells and along the coolant flow path with units, time window, data export format and configuration identifier.
- Archive coolant inlet/outlet temperature difference and estimated pressure drop with units, time window, data export format and configuration identifier.
- Archive heat-balance residual, contact-resistance sensitivity and cooling-system power trade-off with units, time window, data export format and configuration identifier.
What would invalidate a comparison
A lower peak temperature is useful only when temperature uniformity, pressure drop and coolant power are considered together. Avoid assuming that a thermal-only model predicts cycle life.
Do not use mismatched operating conditions or different normalization conventions to claim improved performance. Report the numerical tolerance or controller sampling time where it materially affects the result.
Reporting checklist
Record model fidelity and exclusions; name the data source for each parameter; label whether a result is simulated, measured or calculated from another quantity.
Validate repeatability before expanding parameter sweeps, and preserve a baseline output so later studies can be reproduced.
