Heat flux
Label changes with the case; the source gives these forms: Heat flux, Temperature.
- Control: value (
ValueField) - Value modes: none (plain entry)
- Shown when:
!parent.isConvection && !parent.isRadiation
The in-app guidance depends on the case:
- Positive is heat going into the part.
- Kelvin. 20 °C is 293.15 K.
Film coefficient h
- Control: value (
ValueField) - Unit: W/m²/K
- Value modes: none (plain entry)
- Shown when:
parent.isConvection
Still air is about 5, moving air 25, and water in the hundreds.
Surroundings
Label changes with the case; the source gives these forms: Surroundings, Ambient.
- Control: value (
ValueField) - Unit: K
- Value modes: none (plain entry)
- Shown when:
parent.isConvection || parent.isRadiation
Kelvin. 20 °C is 293.15 K.
Emissivity ε
- Control: value (
ValueField) - Value modes: none (plain entry)
- Shown when:
parent.isRadiation
Infrared emissivity, 0 to 1 — not how the surface looks. Polished metal is about 0.05, oxidised steel 0.8, and almost any paint 0.9 whatever its colour.
Problems reported against this step
The application reports no problems against this step.
… marks a value the application computes at run time, so the source carries no fixed text for it.
