convectiveHeatTransfer

Description

The convectiveHeatTransfer is a boundary condition that provides a convective heat transfer coefficient condition:

• If $Re > 500000$:

$$h_p = \frac{0.664 \mathrm{Re}^{0.5} \mathrm{Pr}^{0.333} \kappa_p}{L}$$

• Else:

$$h_p = \frac{0.037 \mathrm{Re}^{0.8} \mathrm{Pr}^{0.333} \kappa_p}{L}$$

where:

Property	Description
$h_p$	Patch convective heat transfer coefficient
$\mathrm{Re}$	Reynolds number
$\mathrm{Pr}$	Prandtl number
$\kappa_p$	Thermal conductivity
$L$	Length scale

Usage

The condition requires entries in both the boundary and field files.

Boundary file

<patchName>
{
    type            patch;
    ...
}

Field file

<patchName>
{
    // Mandatory entries
    type            convectiveHeatTransfer;
    L               <scalar>;

    // Inherited entries
    ...
}

where:

Property	Description	Type	Required	Default
type	Type name: convectiveHeatTransfer	word	yes	-
L	Length scale	scalar	yes	-
