Abstract: Two types of commingling nozzles have been used to study the air flow behaviour inside the nozzle and their effects on commingling performance of glass/nylon yarns. The air flow behaviour has been analysed with computational fluid dynamics software FLUENT 6.1 and actual air flow velocities are calculated using measured air pressure. It is observed that there is a good correlation between the simulation and the measured air flow pattern. The air flow pattern in the Nozzle-1 configuration shows more turbulent zones than that in Nozzle-2. The commingled yarn properties also clearly indicate that the effectiveness of commingling is much better with Nozzle-1 configuration than that with Nozzle-2 configuration.
