The Workflow StackA first-pass heat exchanger check
Close the energy balance, calculate the counterflow temperature difference, and estimate UA without losing sight of pressure drop or operating limits.
Guides you can use on the next project.
Concise methods for thermal systems, HVAC modeling, and CAE, with examples, limits, and worksheets you can adapt. No account required.
Build a useful heat pump performance map
Organize heating capacity and power by operating condition, then use the map to evaluate low-temperature performance and control decisions.
Run a CFD mesh independence study
Compare engineering outputs across successive meshes, separate iterative from discretization error, and document an honest resolution choice.
A simulation validation checklist
Record the decision, assumptions, numerical checks, independent evidence, and uncertainty in a reviewable model report.
Use these as starting points. Set acceptance criteria for your own hardware, data quality, and project risk.
