atmPlantCanopyTSource
applies sources on temperature, i.e. T
, to incorporate effects of plant canopy for atmospheric boundary layer modelling.atmPlantCanopyTSource
can be applied on any RAS turbulence model.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 |
