Single and multiphase CFD approaches for modelling partially baffled stirred vessels: comparison of experimental data with numerical predictions [PDF]
, 2007 Whilst the use of CFD to study mixing vessels is now common-place, there are still many specialised applications that are yet to be addressed. Here we present CFD and PIV results for a hydrodynamic study of a partially baffled vessel with a free surface.

Analysis of Impeller Type Wind Turbine
IIUM Engineering Journal, 2011 The new global development for wind turbines obliged inventors to create new wind turbine designs that have high efficiency and better than known designs. This paper proposes the impeller wind turbine, which uses more effectively the wind energy and depends only on the acting area of the vanes.
