Bellmouth flow-how??
 

hi,

im trying to demonstrate the flow characteristics of a set of inlet trumpets within an airbox using fluent. i suspect it may be best if i flow one first before arranging the 4 in aline and introducing the parameters of the airbox.

upto this point io have only simulated the trumpet in a wind tunnel situation, this is not ideal as in reality air is drawn through and is actually pulsating.

can anyone point me in the right direction of how to tackle this.

many thanks
