Section: Temperature Sources

temperature.source_terms

type: String(s), optional

Activates source terms for the energy equations. These strings can be entered in any order with a space between each. Please consult the AMR-Wind API for a comprehensive list of all energy source terms available. Note that the following input arguments specific to each source term will only be active if the corresponding source term (the root name) is listed in temperature.source_terms.

DragTempForcing.drag_coefficient

type: Real, optional

This value specifies the coefficient for the forcing term in the immersed boundary forcing method. It is currently recommended to use the default value to avoid initial numerical stability.

The following list of inputs are used with the Temperature.source_terms = PerturbationForcing option to add perturbation to the temperature field to generate flow structures for LES when the inflow data is coarse or uniform flow condition. Not recommended for use with RANS models.

PerturbationForcing.start

type: Real, mandatory

Start location of the perturbation box

PerturbationForcing.end

type: Real, mandatory

End location of the perturbation box

PerturbationForcing.pert_amplitude

type: Real, optional

Amplitude of temperature perturbation

PerturbationForcing.time_steps

type: Real, optional

Separation time between applying perturbations. A high value may dampen the flow structures and a small value may cause numerical instability.
