Though stirred vessels agitated are very common in the chemical and allied industries, the theory of mixing and the design mixing equipment methods are not developed well up to now, the methods of scale-up for agitation equipment rely on correlation among dimensionless group of parameters , empirical methods is still the main tools for design and scale-up industry process. To meet the purpose for optimal design and scale-up and fully understand the processes occurring in stirred vessels, there are needs for...
