Abstract This paper aims to present a numerical investigation of the two-phase flow in unbaffled uncovered stirred tanks equipped with Rushton turbine. The shaft is positioned eccentrically. As simulation software, Simcenter Star CCM+ 2021.2 used carry out multiphase unsteady simulations. Next, results are compared obtained on test bench.

and Overview. In this paper we describe the motivation, design and implementation of a system to visually guide a locomoting robot towards a target and around obstacles. The work was inspired by a recent suggestion that walking humans rely on perceived egocentric direction rather than optic flow to guide locomotion to a target. We briefly summarise the human experimental work and then illustrat...

The impetus for our study was the contention of both Lynn [Lynn, R. (1991) Race differences in intelligence: A global perspective. Mankind Quarterly, 31, 255–296] and Rushton (Rushton [Rushton, J. P.

Computational fluid dynamics (CFD) is a powerful numerical tool that is becoming widely used to simulate many processes in the industry. In this work study of the stirred tank with 7 types of concave blade with CFD was presented. In the modeling of the impeller rotation, sliding mesh (SM) technique was used and RNG-k-ε model was selected for turbulence. Power consumption in various speeds in th...

S u m a r y .-Rushton's (1 988) reinterpretatjon of recent research on brain weight one-sidedly emphasizes the findings of heavier brain weight in whites than in blacks and neglects to comment on a larger difference found between men and women. Rushton explicitly used brain size as indicator of intelligence. His implicit conclusion chat women are less intelligent than men is not supported by em...

The hydrodynamics of stirred tanks and bubble breakup are crucial in gas-liquid flows, yet this system has not been well characterized for different operating conditions. In work, the numerical method was used to investigate six- flat blades impeller (Rushton turbine) results were employed understand behavior tank. Simulation predicted flow pattern, power number, distribution turbulence energy ...
