2.2 Water is not stratified

 

In this case, the picnocline or thermocline has been formed. We will distinguish the following cases:

 

2.2.1 Multiport diffuser.- In such a case, we have the next equations

 

ymax=2,84 (g’q)1/3 Г -1/2

S=0,31 g’1/3 ymax q-2/3

B=max[Ltsin θ; 0,93Lt F-1/3]

e=SQ/BUa

 

where Г=-(g/ρ)dρa/dy is the stratification coefficient (s-2) and ymax is the thickness of the mixing layer (m).

 

2.2.2 Separated ports.- In such a case, we have the next equations

 

ymax=3,98 (g’Qb)1/4 Г -3/8

S=0,071 g’1/3 y5/3max Qb-2/3

B=max[Ltsin θ; 0,93Lt F-1/3]

e=SQ/BUa

 

2.2.3 Single port.-

 

ymax=3,98 (g’Q)1/4 Г -3/8

S=0,071 g’1/3 y5/3max Q-2/3

e=0,13 ymax

B=SQ/eUa

 

For a profile of velocities different from the previous ones, it will be required a more complex method of numeric integration to solve the problem.
