based on materials mass balances shows that the mathematical model representing the alcoholic fermentation kinetics can be represented by:
 

============================> look at it on the scan document….

 
S Substrate Concentration

X Biomass Concentration

P Product Concentration

V Reactionnal Volume
Qin Inflow

Qmass Flow output

Sm Substrate Feed Concentration

U Specific growth rate of the biomass

Umax Maximum Specific growth rate of the biomass

Ks Affinity constant of the substrate relative to the degradation of the substrate

Pin Inhibition coefficient alcohol

Ki inhibition constant relative to the degradation of the substrate

K’s Affinity constant of the substrate relative to the substrate alcohol production

K’i Inhibition constant relative to the production of alcohol

Vs Rate specified degradation of the substrate

Vp Rate specified alcohol production
 
Vmax Specific maximum rate of production of alcohol

Y’ Performance conversation substrate production

D Dilution ratio

Are the following initial conditions : X(0) = Xo ; S(0) = So ; P(0)= Po
Question
1. simulate the model presented above in continuous mode for 14 hours fermentation by considering the following data
Characteristic of the initial point :

S0 = 20 g.l’1
X0 = 1 g.l’1
P0 = 0 g.l’1
Characterization of the method:
V = 1 I
Qin = 0.1 l.h-1
Qm = 0.1 l.h-1
Sin = 20 g.l-1

Characterization of the kinetics of alcoholic fermentation:

Umax = 0.4 h-1

Ks = 5 g.l-1

Pm = 70 g.l-1

K1 = 201 g.l-1

Vmax = 1.4 h-1

K’s = 9 g.l-1

K’i = 297 g.l-1

Yp = 0.48 gp.gs-1
 

 
Question 2. Analyze, or identifier or study the sensitivity of kinetic parameters: Umass, Ks, Pm, Kin, Vmass, K’s, K’i, Yp
 

 
Question 3. Alcoholic fermentation was conducted experimentally under the same conditions as those provided by the simulation of detailed model above. The ethanol concentration was measured and the values ​​are detailed in the following table.

Can someone help right now please I will pay you $40 dollar
my email is ibrahimdem@hotmail.fr
So I can send you the detail I have a scan document that I couldn’t join it on here
