Spinning fluids reactor (SFR) is one of the most efficient gas-liquid contacting system with high potential of application in many fields. The unique solution of SFR is the contacting of two spinning fluids which generated centrifugal force. The aim of this study was to investigate the pressure field distribution on the inner surface of reactors dispersing element. Obtained results confirm the high heterogeneity of the field pressure in the reactor system with a cylindrical wall. This is due to the low tangential force generated by rotating liquid on a cylindrical wall, and pressure drop in the locations of surface irregularities. The change of the sparger element to conical shape element increases the pressure exerted by fluid on the wall. In this case the effects of solid particles and inequality in the fluid flow are negligibly small compared to the measured pressure exerted on the sparger element.
