Mixing Efficiency of Mixing tee

We will consider 3 cases for mixing tee

•Case 1 for short mixing tee with

⇒Hot inlet velocity=3m/s

⇒Cold inlet velocity=6m/s

Now the convergence plot for this case can be seen below

•Cutplane in middle of pipe coloured with temperature and velocity is shown below

For Case 1

Cell Count = Elements- 11635 Nodes- 2582

Average Outlet Temperature=19.5 ºC

Number of iterations for convergence=400

•Case 2 for Long Mixing tee

⇒Hot inlet velocity=3m/s

⇒Cold inlet velocity=6m/s

Convergence plot for velocity and temperature can be shown below

•Cutplane in middle of pipe coloured with temperature and velocity for case 2 is shown below

For Case 2

Cell Count = Elements-16042 Nodes-3560

Average Outlet Temperature= 21.5 ºC

Number of iterations for convergence=470

•Case 3 for Short Mixing tee

⇒Hot inlet velocity=3m/s

⇒Cold inlet velocity=12m/s

Convergence plot for velocity and temperature can be shown below

•Cutplane in middle of pipe coloured with temperature and velocity for case 3 is shown below

For Case 3

Cell Count = Elements- 11635 Nodes- 2582

Average Outlet Temperature= 18.8 ºC

Number of iterations for convergence=300
