Partial function for convective heat flux

### Information

Partial function that is used to implement the convective heat flux as

q̇ = h ΔT,

where
*ΔT* is the solid temperature minus the fluid temperature and
*h* is the convective heat transfer coefficient.

Extends from Modelica.Icons.Function (Icon for functions).

### Inputs

Type | Name | Default | Description |
---|---|---|---|

TemperatureDifference | dT | Temperature difference solid minus fluid [K] |

### Outputs

Type | Name | Description |
---|---|---|

HeatFlux | q_flow | Convective heat flux from solid to fluid [W/m2] |
