A numerical study of air flow in a coaxial pipe
A simulation study of a cold-flow in coaxial pipes was carried out with varying drivepipe diameter and entrance displacement (?L). The current work has studied the effect of the temperature of the entrance flow inlet with variation of ?L to the entrained flow characteristics. To predict these flo...

| description | A simulation study of a cold-flow in coaxial pipes was carried out with varying drivepipe
diameter and entrance displacement (?L). The current work has studied the effect of the temperature
of the entrance flow inlet with variation of ?L to the entrained flow characteristics. To predict these
flow characteristics, a numerical method was employed by the differencing scheme for integrating the
continuity equation and energy equation. A k-? turbulent model was used to simulate the turbulent
transport quantities. The 2-D flow pattern was created as the result of using Fluent version 4.4 CFD
modeling package. Results showed that increasing the air entrained temperature until 600 K would
decrease the airflow rate. It was found that the diameter ratio of 2.81 has the highest entrained flow rate |
