Detailed Description

Templated class to calculate the fluid-particle heat transfer coefficients based on a specified Nusselt-number model.

$h = \frac{\mathrm{Nu} \, \kappa}{d_p}$

where

	=	Convective heat transfer coefficient of the flow
$\mathrm{Nu}$	=	Nusselt number
$\kappa$	=	Thermal conductivity of carrier in the film
	=	Particle diameter

Optionally, Bird-Stewart-Lightfoot correction can be applied to correct the heat transfer coefficient for evaporation:

$h_{corr} = h \, \frac{\beta}{ \exp(\beta) + 1 }$

with

$\beta = \frac{N \, C_p \, W}{h}$

where

$\beta$	=	Correction factor
	=	Molar flux
	=	Specific heat capacity
	=	Molecular weight

Usage

Minimal example by using constant/<CloudProperties>:

subModels
{
    heatTransferModel    <model>;

    <model>Coeffs
    {
        BirdCorrection   true;
    }
}

where the entries mean:

Property	Description	Type	Reqd	Deflt
`heatTransferModel`	Type name: <model>	word	yes	-
`<model>Coeffs`	Model properties	dict	cndtnl	-
`BirdCorrection`	Flag to apply Bird-Stewart-Lightfoot's correction to the heat transfer coefficient	bool	cndtnl	-

Options for the <model> entry:

      RanzMarshall   | Ranz-Marshall correlation for Nusselt number
      none           | No active model
