Mixing and flow patterns in an isothermal, turbulent, confined, swirling jet system

Experimental investigations were carried out to determine the mixing and flow patterns in a confined, isothermal, swirling jet system over a range of operating conditions in terms of graft determines the reaction rate at high flow rate. The experimental data were compared with the theoretical solutions and it was seen that at low flow velocities the experimental reaction rates agreed with the theoretically predicted rates. At high flow rate the reaction rate is independent of flow rate. Under these conditions, it was found that the reaction rate is virtually determined by the kinetics of enzyme reaction, the internal diffusion resistance being relatively unimportant. The storage stability of the immobilized CT films and the operational life of the immobilized CT tubular reactor were also studied. It was seen that immobilized CT retained its activity over considerably longer periods than did free CT when stored at pH 7.8 and 25 deg.
