Stirred aerated tanks by double impellers are used in fermentation and various biological
processes for water treatment, food industry, and pharmaceutical production. In this study, a
generalized correlation model was developed for the dependent parameter (kla/N). The
oxygen mass transfer from air to liquid takes place by rotating the double impellers (IBRC
and PBPU) in the aerated tank. This model considers Reynolds number, Froude number,
power number, the liquid height, and the spacing between impellers as the most significant …
