TANGENTIAL VELOCITY
« on: March 17, 2016, 05:02:12 am »

HI,
CAN ANY ONE ADVISE ON HOW TO ENTER TANGENTIAL VELOCITY FOR A SIMULATION OF A JET FAN HAVING AN OUTLET AIR VELOCITY OF 24 M/S AT 30° IN THE NORTH-EAST DIRECTION??

If you are modeling the jet fan using the HVAC system, you can use the [ ] Louver option in the HVAC Properties of the vent. For a particular angle, use a polar to cartesian coordinate calculation and assume r=1. Example:

x=cos(30*)
y=sin(30*)
z=0

The velocity is set in the HVAC fan element.
