Investigations of mixing in a fluid Jet agitated tank

Mixing in a fluid jet agitated tank: effects of jet angle and elevation and number of jets

“…Fig. 2 shows a comparison of mixing times as a function of Reynolds number as predicted by Zughbi and Rakib (2002) with the mixing times measured by Lane and Rice (1982). A good agreement is shown between the experimental results of Lane and Rice (1982) and the simulation results.…”

“…The basic model developed by Zughbi and Rakib (2002) has been further developed and used in this study to investigate the e ects of the jet angle and elevation and number of jets on mixing in a uid agitated tank. Fig.…”

“…However, poor agreement was observed between the numerical and experimental results of concentration proÿles as a function of time at various locations. Zughbi and Rakib (2002) presented a CFD model of mixing in a uid jet agitated tank and validated their numerical model against the experimental results of Lane and Rice (1982). Malguernera and Suh (1977) indicated that the mixing performance is a function of the jet Reynolds number.…”

Quantification and prediction of jet macro-mixing times in static microwell plates

“…A number of CFD models have been proposed that have emphasised the need to minimise or eliminate dead zones within a large vessel (Jayanti, 2001). These predict overall mixing times (Patwardhan, 2002;Zughbi and Rakib, 2002) and have investigated the effects of the jet position and the number of jets (Zughbi and Rakib, 2004) on macro-mixing within a vessel.…”

Recurrence Quantity Analysis of the Instantaneous Pressure Fluctuation Signals in the Novel Tank with Multi-Horizontal Submerged Jets

“…Ranade 12 investigated the flow patterns and mixing performances in jet mixing tanks using the standard κ-ε model. Simulations of mixing performance in various vessel configurations have been conducted as shown in the References of Jayanti 13 , Zughbi and Rakib 14 . Patwardhan and Thatte 15 investigated the effects of jet velocity, nozzle clearance, liquid depth, and tank size on mixing time with the help of CFD modeling.…”
