Detailed Description

Applies a variable heat transfer model depending on local values for inter-region heat exchanges.

The area of contact between regions (area) must be provided. The Nu number is calculated as:

\[ Nu = a \, \textrm{Re}^b \, \textrm{Pr}^c \]

and the heat transfer coefficient as:

\[ htc = \frac{\textrm{Nu} \, K}{ds} \]

where

$ htc $ = Heat transfer coefficient
$ Nu $ = Nusselt number
$ Re $ = Reynolds number
$ Pr $ = Fluid Prandtl number
$ K $ = Heat conduction
$ ds $ = Strut diameter
$ a, b, c $ = Model constants

Required fields: 

      AoV       | Area per unit volume of heat exchanger    [1/m]
Usage
Minimal example by using constant/fvOptions: 
variableHeatTransfer1
{
    // Mandatory entries (unmodifiable)
    type             variableHeatTransfer;

    // Optional entries (runtime modifiable)
    UNbr             U;
    a                0.0;
    b                0.0;
    c                0.0;
    ds               0.0;
    Pr               0.0;

    // Mandatory/Optional (inherited) entries
    ...
}

where the entries mean:

Property Description Type Reqd Dflt
type Type name: variableHeatTransfer word yes -
UNbr Name of operand neighbour velocity field word no U
a Model constant scalar no 0
b Model constant scalar no 0
c Model constant scalar no 0
ds Struct diameter scalar no 0
Pr Fluid Prandtl number scalar no 0
