Numerical investigation of effect of aeration rate on ethanol production

Numerical methods had many advantages over solving differential equation for optimization of process parameters. Study was carried out for different ranges of oxygen flow rate on aerobic fermentation under controlled condition with differential equation of Monod Model to utilize Numerical method. From 300-450 ml/min with step size of 50 ml/min, oxygen ranges were used for numerical investigation. Maximum ethanol concentration for use of Monod model was obtained at 350 ml/min about 78 g/l. for numerical technique compared with experimental results the maximum ethanol concentration observed at 78g/l. with use of numerical technique we can easily make optimize condition for any process without any experimental setup.
