Calculation of Power Number,Flow Number of Axial Flow Impeller and Distribution of Dissipated Energy in Stirred Tank

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.The influences of blade laying angle,solidity, blade shape,profile,blade relative thickness and impeller/hub ratio on the characters of impeller are calculated.
