rahim New Member Rahim Join Date: Jul 2010 Posts: 6 Rep Power: 16	I want to simulate tunnel venyilation system by jet fans placed inside it using Fluent 6.3. However, there are some problems in the definition of jet fan boundary conditions as follow: 1. How do i define the zone or zones? I can not understand that a jet fan inside the tunnel consisted of one zone or two zones? 2. Which boundary conditions are appropriate for inlet, outlet and walls of the jetfan with respect to its pressure jump? I will be happy if any one sends your replies to Hassanzadeh.rahim@gmail.com Sincerely
