The objective of this study was to develop a new mixing element and to perform the experimental<br/> investigation of flow and mixing in a static mixer that could equipped the new element and the others.<br/> Glycerin, hydraulic oil and gear oil were used as mixing fluids. Pressure drops across the static mixer<br/> elements of different designs and different numbers were measured using a hydraulic manometer. The axial<br/> and cross-sectional views of tracer mixing were photographed using a digital camera. The pressure drops of<br/> SSM mixer were about 20% less than that of Sulzer mixer whereas the mixing performance of SSM mixer<br/> was not so good as that of Sulzer mixer.

Heat transfer augmentation based on the process intensification concept in heat exchangers and thermal reactors has received much attention in recent years, mainly due to energy efficiency and environmental considerations. The concept consists of the development of novel apparatuses and techniques that, compared to those commonly used today, are expected to bring dramatic improvements in manufacturing and processing, substantially decreasing equipment size, energy consumption, and ultimately resulting in cheaper, sustainable technologies. The objective of this paper was to investigate the heat transfer characteristics of tubular thermal reactor using static mixing technology. Glycerin and water were used as the test fluids and water was used as the heating source. The results for heat transfer rate were strongly influenced by tube geometry and flow conditions.
