Abstract
Rate of gas induction, static pressure, mixing time and power consumption have been measured in
0.57 m i.d. vessel. Different types of impellers namely shrouded disc turbine, shrouded curved blade
turbine and pitched blade turbine were used. The impeller diameter was varied from 0.15-0.25 m and
the impeller speed was varied from 3 to 20 r/s.
The pitched blade turbine was found to give 30-60 per cent higher rates of gas induction as
compared with the best design reported in the literature. The mixing time was found to be lower by a
similar magnitude. Moreover in the case of pitched blade turbine it was found that the gas was getting
induced radially as well as axially. This eliminates the necessity of the diffuser and hence reducing the
complexities in the mechanical structure.
