Which turbulence model to use and which equations I should use to estimate the turbulence energy and length scale

Describe your problem in detail. What are you trying to investigate. Do you want to look for the flow structures inside the duct or your primary goal is something else?

We are designing a luggage rack for a bus. The total length is 14 m, and the luggage rack is the air duct for the Air condition system. The blower are going to be in the middle of the duct. The main target is to have the same flow of air on the outlets of the duct. What we need is to have the same temperature inside of the bus in the front , middle and rear of the bus. To achieve this we need the same mass or flow of the air on each part of the bus. The simulation is to determine how many outlets and the correct distribution.
