Mixing efficiency

	cell count	ave.out.Temp.	no. Iteration
case 1(k-e)(2and4)	21977	(30.25 and 27.5)	350
case 1(k-w)(2and4)	21977	(30.25 and 27.5)	350
case2(K-W)(2and4)	28898	(30.38 and 27.5)	350

There is no difference in mixing temperature for case 1 and case 2.

k-e and k-w are RANS based method for evaluation.

k- epsilon model predicts well far from the boundaries (wall) and k- omega model predicts well near wall, it has SST model which is a combination of these.
