Experimental Verification of Model Prediction

Nevertheless, no published data are available regarding the important aspect, i.e., the inside concentration distribution of an equipment. Thus, experimental work was conducted for the purpose of obtaining the concentration distribution in the equipment for the comparison with model prediction. 

The experimental installation [22] is shown schematically in Fig. 3.3 for the desorption of dissolved oxygen in water by blowing air. 

The liquid-phase-gas-phase-interaction model (interacted liquid-phase model) accompanied with c — Sc model as described in preceding sections were used to predict the concentration distribution and compared with the experimental data as shown in Fig. 3.5. 

As seen from Fig. 3.5, the model predictions are reasonably agreed with the experimental measurement in consideration of some inaccuracies involved in both simulation and experiment. The obvious discrepancy between the experimental 

As shown in preceding chapters, on the basis of Boussinesq postulate, the Reynolds stress —pu Uj, Reynolds heat flux —piifT, and Reynolds mass flux —u f (or —pujc ) can be expressed respectively as proportional to their gradients of average velocity, temperature, and concentration
