Figure Lengend Snippet: CFD models showing velocity contours for a cross-section at 50% reactor depth at 60 s of a 2L Asynt overhead stirrer tank reactor at various stirring rates, with and without baffle insert, using a four-bladed 45° pitch-blade turbine. Dynamic viscosity, μ = 0.0009 kg m –1 s –1 .

Article Snippet: To simulate stirring and baffle effects, we generated CFD models for our bespoke 2L Asynt overhead stirred tank reactor and pitch-blade turbine impeller, both with and without a beaver tail baffle insert.

Techniques: Viscosity

Figure Lengend Snippet: b * profiles of Villermaux–Dushman reactions to investigate the impact of HCl feed position in 2L tank reactor. HCl injection from the subsurface zone led to detection of higher yellow coloration than injection in the impeller zone. More positive b * values infer more yellowing at a given point in time relative to lower (more negative) b * values. Green circles shown on the inset images show the subsurface and impeller zone feed points. Stirring rate = 120 rpm.
