- Axial polar ventilation ducts schematics
In MANATEE, to define axial polar ventilation ducts, the first thing to do is to select the corresponding type :
Input.Thermics.type_axial_ductr=2; Then one need to set several parameters : Number (Navd), Ventilation position (Havd), Height (Davd) and angular width (W1avd). As the ventilation can be added both on the rotor and on the stator, a letter is added at these names to distinguish them (’s’ for stator and ’r’ for rotor).
- Machine with polar ventilation ducts
This configuration is generated with MANATEE by using the following set of variables for the rotor ventilation ducts:
Input.Thermics.type_axial_ductr=2;
Input.Thermics.Navdr =[8];
Input.Thermics.Davdr =[5e-3];
Input.Thermics.W1avdr = [0.2];
Input.Thermics.Havdr =[72.5e-3]; One can see that the parameters Navd, Davdr, W1avd and Havdr are vectors. This allow to define several set of ventilation ducts. The following code define 3 set of ventilation ducts:
Input.Thermics.type_axial_ductr=2;
Input.Thermics.Navdr = [4,8,16];
Input.Thermics.Davdr = [5e-3,10e-3,15e-3];
Input.Thermics.W1avdr = [5e-3,10e-3,20e-3];
Input.Thermics.Havdr = [60e-3, 70e-3, 85e-3]; Navdr, Davdr, W1avdand Havdr must have the same length. Every set share the same index in each vector (set 1 is 4 ducts with Davd= 5e-3, Havd=60e-3...)
