Week 1- Mixing Tee
project: mixing Tee
case.1: short mixing tee
a.
Momentum ratio: 2
hot inlet temp: 36 c
cold inlet temp:19 c
hot inlet velocity: 3m/s
cold inlet velocity: 6m/s
case_1B.
Momentum ratio: 4
hot inlet temp: 36 c
cold inlet temp:19 c
hot inlet velocity: 3m/s
cold inlet velocity: 12m/s
in case 1 , study of short mxing tea with momentem ratio 2 and 4.
1. it was found when momentuam ratio increase the number of iterations for convergence is decrese.
2. its was found when momentm ratio incresse the avg outlet temp also increase.
case_2: long mixing tee
a.
Momentum ratio: 2
hot inlet temp: 36 c
cold inlet temp:19 c
hot inlet velocity: 3m/s
cold inlet velocity: 6m/s
b.
Momentum ratio: 4
hot inlet temp: 36 c
cold inlet temp:19 c
hot inlet velocity: 3m/s
cold inlet velocity: 12m/s
in case 2 i found that,
1. the momentum ratio increase the avg oulet velocityalso increase.
