Main hypothesis

- Steady-state RANS for neutral simulations

- Accounts for atmospheric stability by adding an additional energy conversation equation formulated in terms of the potential temperature and using the k-epsilon closure scheme. Surface conditions are determined via heat flux or temperature gradient.

- Actuator Disk Modelling for Wakes
