Blade row number
WebThe goal of turbomachinery CFD simulations is to predict flow behavior in adjacent rotating and non-rotating blade rows. This means multiple frames of reference need to be used: “moving” for the rotating parts and “stationary” for the non-rotating. The link between these rotating and stationary frames of reference is called the Rotor ... WebBlade Solidity = c/s; Where = / is the spacing is the mean radius; is blade number; Chord length c is the length of the chord line; In case of an axial flow impeller mean radius is …
