Hi CFDians,

i am simulating the air flow in a rectangular channel. and cotton(fiberous material) is to be passed through the channel with air flow. the channel is connecting two consective machines in textile spinning mill. at the inlet positions of the channel an opening roll is there. air is flowing by suction at the outlet of the channel. only air velocity through the channel is known. currently i am using velocity inlet boundary conditions. plz suggest boundary conditions if i am not using the right boundary conditions.

with regards

Abdul Moqeet
