in which stirred vessels are found , from ore processing and polymerization to effluent treatment and fermentation processes including biopharmaceuticals . The same principle also allows for research with model fluids to simulate conditions in bioreactors or other extreme conditions without need to employ the real systems , thus enabling data to be obtained within reasonable cost ( see Figures 4a and 4b ).
Stirring is the mechanism to promote bulk movement which in turn facilitates the
