Hi All,
Computational fluid dynamics a very powerful concept of
optimizing air flow and predicting thermal comfort of a building in
terms of temperature, air circulation, contaminants etc however
applying a correct boundary condition is a time consuming work as the
boundary conditions varies our results varies over a range recently i
seen a cfd online query where one user has used velocity as inlet
condition and pressure as a outlet condition for naturally ventilation
a room with heat a generating source inside room how far is this
condition justified.
Thanks
Sambhav

and airflow simulation.
