Fluid mixing is ubiquitous and essential in many natural and industrial systems. Understanding the mixing processes that occur in these diverse systems is essential for predicting many aspects of practical importance. The objective of this study was to develop a new mixing element and to perform the experimental investigation of flow and mixing in a static mixer that is equipped the new element and the others. Glycerin and gear oil were used as mixing fluids. Pressure drops across the static mixer elements of different designs and different numbers were measured using a hydraulic manometer The axial and cross-sectional views of tracer mixing were photographed using a digital camera. The pressure drops of SSM mixer were about 20% less than that of Sulzer mixer whereas the mixing performance of SSM mixer was not so good as that of Sulzer mixer
