Week 1- Mixing Tee
case 1
- Short mixing tee with a hot inlet velocity of 3m/s.
Geometry
mesh
*autometed genaretd mesh
total number of nodes 2881
total number of elemants 123984
- Momentum ratio of 2.
Residuals graph
Number of iterations for convergence at 420
total number of iterations given -700
velocity change in the middle of plane
it shows that yinlet (cold air) have velocity given
Temperature variation line graph
we can see that high temperature at inlet nearly 300k but at outlet 300k
