This retrospective essay appraises J. Philippe Rushton’s application of life history to understanding the covariation among human traits in light of subsequent developments in the measurement and latent structure of Human Life History, covitality, and personality. We conclude that Rushton should be recognized for having initiated a theoretically and empirically highly fertile paradigm in human ...

Three-dimensional laser Doppler Anemometry measurements of the turbulent flow field in the vicinity of the baffles in a vessel agitated with a Rushton turbine have been performed. The measurements have provided simultaneously all three components of the instantaneous velocity, and thus information on all elements of the Reynolds stress and anisotropy tensors in addition to data on flow field an...

BACKGROUND Mass transfer plays an important role in determining the efficiency of the biofuel conversion. However, adverse effect of shear stress from traditional agitation inhibits the cell growth and production of biofuels. How to enhance the mass transfer with less adverse effect is considered as one of the important bioengineering issues. RESULTS In this study, a novel agitation type, nam...

The turbulent flow field generated in a baffled stirred tank was computed by large eddy simulation (LED) and the flow field was developed using the Sliding Mesh (SM) approach. In this CFD study, mixing times and power number have been determined for a vessel agitated by a 6-blade Rushton turbine. The predicted results were compared with the published experimental data. The satisfactory results ...

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.
