atmPlantCanopyTSource

- The
`atmPlantCanopyTSource`

applies sources on temperature, i.e.`T`

, to incorporate effects of plant canopy for atmospheric boundary layer modelling. - The
`atmPlantCanopyTSource`

can be applied on any RAS turbulence model. - The
`atmPlantCanopyTSource`

inherits the traits of the fvOption, and`cellSetOption`

.

Corrections applied to:

T | Temperature [K]

Required fields:

T | Temperature [K] qPlant | Tree-height based specific heat flux [m2/s3]

The model expression:

\[ f_M += \alpha \rho \frac{q_{plant}}{C_{p_0}} \]

where

\( f_M \) | = | fvMatrix of the temperature field [K/s] |

\( q_{plant} \) | = | Tree-height based specific heat flux [m2/s3] |

\( C_{p_0} \) | = | Specific heat capacity [m2/s2/K] |

\( \alpha \) | = | Phase fraction in multiphase computations, otherwise equals to 1 |

\( \rho \) | = | Fluid density in compressible computations, otherwise equals to 1 |

Example of the fvOptions specification using `constant/fvOptions`

file:

atmPlantCanopyTSource1 { // Mandatory entries (unmodifiable) type atmPlantCanopyTSource; atmPlantCanopyTSourceCoeffs { // Mandatory (inherited) entries (unmodifiable) selectionMode all; // Optional entries (unmodifiable) rho rho; Cp0 1005.0; } // Optional (inherited) entries ... }

where the entries mean:

Property | Description | Type | Required | Default |
---|---|---|---|---|

type | Type name: atmPlantCanopyTSource | word | yes | - |

rho | Name of density field | word | no | rho |

Cp0 | Specific heat capacity [m2/s2/K] | scalar | no | 1005.0 |

The inherited entries are elaborated in:

- fvOption
`cellSetOption`
