Modeling the Risk of a Failed Wind Turbine Blade Impacting a Power Transmission Line [PDF]
, 2009 Wind turbine installations are generally situated in proximity to power transmission lines that integrate generated power into the grid. Failure of a wind turbine that results in a blade or blade fragment thrown from the rotor can result in impact with a

EFFECT OF IMPELLER BLADE THICKNESS ON CRITICAL IMPELLER SPEED IN AN AGITATED VESSEL
Scientific Study & Research: Chemistry & Chemical Engineering, Biotechnology, Food Industry, 2017 The successful design and operation of solid-liquid agitators require proper prediction of critical impeller speed (Njs) needed to suspend solids. It depends on system and impeller geometry as well as the properties of both solid and liquid.

Experimental Investigation of Microbubble Evolution in the Liquivac Multiphase Flow Pump
Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT This paper aims to experimentally investigate the mechanisms of microbubble characteristics evolution within an axial pump. The findings will aid in assessing the pump performance by identifying the range of bubble sizes and comparing them with the threshold size (< 300 μm). This study also provides evidence supporting the use of such pumps as
