pitched blade impellerPrevious studies of the Rushton turbine have shown that the power number is sensitive to the details of impeller geometry, and in particular to the blade thickness, but is independent of the impeller diameter to tank diameter ratio. In this paper, a similar study is ...
The calculation formulas of power number,flow number of axial flow impeller and distribution of dissipated energy in stirred tank are derived according to the equations of force and momentum balance. 从搅拌桨的力与力矩平衡这两个基本方程出发,推导出轴流桨功率准数、流量准数与搅拌釜内能耗分配的理论...
impeller to improve the utilization efficiency of offshore wind and the number of utilizable hours per year, resulting in lower generating costs. SeeFig. 6.1for the changes in the leading indicators of wind power generators in 1998–2013. The single-unit capacity of wind turbines is expected ...
The Effect of Impeller and Tank Geometry on Power Number for a Pitched Blade Turbine Previous studies of the Rushton turbine have shown that the power number is sensitive to the details of impeller geometry, and in particular to the blade t... D.,Chapple,and,... - 《Chemical Engineering ...
In-line rotor stator mixers differ from in-tank versions because the flow is often controlled independently of the rotor speed. For in-tank devices the turbulent power can be adequately described by single impeller type power number. For an in-line rotor-stator mixer it is found that the powe...

It was observed that the impeller power was significantly affected by the conditioning variables. A range of solids loading and agitation speeds exists in which the classical power number-Reynolds number correlation was found to hold true. The impeller power was found to be influenced by the ...
Power consumption displays the performance of the agitating process depending on the geometry of the impeller and the physical properties of the fluid. In the present work, power consumption (Po) is used as a parameter in order to evaluate the efficiency of the proposed new close-clearance impel...
While there are a number of different power cycles, the most commonly used for large-scale power generation are the Brayton cycle and the Rankine cycle (Fig. 1.1). A simple observation reveals that the Brayton cycle lies completely within the single-phase gas region, while the Rankine cycle ...
