2.1 Water is stratified

2.1.1 Multiport diffuser.- We have three different cases:

Case I:

θ >=65º F<=0.1 ó

θ <65º F<=0.36

θ=angle between U_a vector and diffuser.

F=Fraude number F=Ua³ (g’q)^-1

q=Unitary flor rate in the diffuser q=QL_t^-1 (m²/s)

Q=Discharge flow rate (m³/s)

L_t=Diffuser length (m)

S=initial dilution

In such a case, we have the next relationships

S=0.27 U_a H q^-1 F^-1/3

e=0.29H

B=SQ/eU_a

Case II:

25^o=<θ <65º F>0,36 (*)

In such a case, we have the next relationships

S=0.38 U_a H q^-1

B=max[L_tsin θ; 0.93L_t F^-1/3]

e=SQ/BU_a

Case III:

θ <25º 0,36<F=<20

In such a case, we have the next relationships

S=0.294 U_a H q^-1 F^-1/4

B=max[L_tsin θ; 0.93L_t F^-1/3]

e=SQ/BU_a

Case IV:

θ <25º F>20

In such a case, we have the next relationships

S=0.139 U_a H q^-1

B=max[L_tsin θ; 0.93L_t F^-1/3]

e=SQ/BU_a

Case V:

θ >65º F>0,1

In such a case, we have the next relationships

S=0.58 U_a H q^-1

B=max[L_tsin θ; 0,93L_t F^-1/3]

e=SQ/BU_a

From Case II to Case V, and if e>H, we take e=H and S= U_aBH/Q.

2.1.2 Separated ports.- We will solve this case by means of a iterative mathematical method

B=max[L_tsin θ; 0,93L_t F^-1/3]

S=0.089 g’^1/3 (H-e)^5/3 Q_b^-2/3

e=SQ/BU_a

Q_b= flow rate at each single port(m³/s).

The number of iterations can modify by means of the parameter N_it of the function Calculation parameters of the program.

Increasing N_it value, we increase the numeric convergence but we will need more time of calculation. We should look for an optimized value of N_it.

Single port.- In such a case, we have the next relationships

e=0.15H

S=0.089 g’^1/3 (H-e)^5/3 Q^-2/3

B=SQ/eU_a (*)

However, at high velocity values and if B<=0.3H, the approximation is not correct .
