Plane wave propagation inside a duct (Vibroacoustic)
Posted May 23, 2012, 9:42 AM EDT Studies & Solvers, Structural Mechanics & Thermal Stresses Version 4.1 5 Replies
I me dealing with an interesting vibroacoustic problem and wanna model it WIth COMSOL.
The subject is : A duct (Air inside)of one meter length and cross sectional 0.2m*0.2m (width=1m)
Boundary conditions : unit velocity at one end
zero velocity Boundary condition is applied at the other end (rigid wall)
The 4 lateral sides are assigned rigid wall.
Frequency = 100hz.
Material (duct) = Any (wood, alu,etc...)
My questions are :
- COMSOL doesn't contain Velocity boundary ? (Drive me mad)
- How to handle that with COMSOL ?
Your help would be very appreciated .......
Thanks in advance.
