WebIn a Newtonian fluid, rotation will not affect the axial flow, although “centrifugal throwing” is still important. Note that in an initially steady, concentric non-Newtonian flow, where the mud pump is operating at constant pressure, a momentary increase in rpm leads to a temporary surge in flow rate and thus improved hole cleaning.
