Analytical Properties
|
| Heat Transfer Coefficient (U) |
Used in calculating the heat transfer, typically by convection or phase change between a fluid and a solid. |
| Heat Transfer Coefficient (U) |
A measure of a temperature difference, by which an object, or material, resist a heat flow (heat per time unit or thermal resistance. |
| Thermal mass |
Equivalent to thermal capacitance or heat capacity. |
| Absorptance |
A measure of the ability of an object to absorb radiation, equal to the ratio of the absorbed radiant flux to the incident flux. |
| Roughness |
A measure of the texture of a surface. |
