By a News Reporter-Staff News Editor at Journal of Engineering -- A new study on Chemical Engineering is now available. According to news reporting out of Tianjin, People's Republic of China, by VerticalNews editors, research stated, "The fractal structures of flow images of gas liquid solid circulating fluidized beds (GLSCPBs) with low solid holdups of macroporous resin particles at different operating conditions and liquid physical properties were investigated by the fractal analysis method. The images were obtained with the high-speed image acquisition and treatment system of complementary metal oxide semiconductor (CMOS)."
Our news journalists obtained a quote from the research from the State Key Laboratory of Chemical Engineering, "The results show that the structure of the gas liquid solid circulating flow exhibits certain fractal behavior and the fractal dimension D can be used to describe the multiphase self-organization flow structure from the point of view of geometry. The fractal dimension changes with the phase holdup and the agglomeration degree of bubbles or/and particles. Generally, higher solid or gas holdup leads to larger fractal dimension and more extensive aggregation or self-organization degree results in lower entropy and thus lower fractal dimension."
According to the news editors, the research concluded: "In order to avoid the appearance of the aggregation in the GLSCFB riser, higher superficial velocity of primary liquid flow, lower superficial velocity of auxiliary liquid flow, and lower liquid surface tension may be exerted."
