The mixing time of impact zone in liquid-continuous impinging streams reactor (LISR) is theoretically calculated by empirical model and modern micromixing model of the fluid mixing process, and the variation laws of macromixing time and micromixing time are quantitatively discussed. The results show that under a continuous and stable operating condition, as the paddle speed increases, the macromixing time and micromixing time calculated by the two models both decrease, even in a linkage equilibrium state. Simultaneously, as the paddle speed increases, the results figured by the two models tend to be consistent. It indicates that two models both are more suitable for calculation of mixing time in high paddle speed. Compared with the existing experimental results of this type of reactor, the mixing time computed in the speed of 1500 r/min is closer to it. These conclusions can provide an important reference for systematically studying the strengthening mechanism of LISR under continuous mixing conditions.

“…This is due to the increase in continuous phase velocity, enhancement of the residence time of particles as the result of vibratory agitation within the impingement zone, high mixing intensity and turbulent flow within impingement region which improve overall mass and heat transfer coefficients [12]. In order to improve IS reactors capability, a new configuration has been presented by Tamir et al [13]. In such a reactor inlet streams entered the reactor tangentially, rather than counter-currently on the same axis.…”

“…Several experimental studies have been conducted on various systems that employ IS, and a number of advantages have been obtained such as very high efficiency of these kinds of unique streams Sun et al, 2006;Berman and Tamir, 2004;Sohrabi and Jamshidi, 1997;Tamir, 1986;Tamir et al, 1984). To our knowledge, just a few articles have focused on the study of impinging stream characteristics from the viewpoint of mathematical modeling.…”

“…High efficiency, quality of products, great drying intensity, short time, and low energy consumption are among the advantageous characteristics of an ISD, and impinging stream dryers are also expected to have a wide application in engineering processes (Huai et al, 2003). Tamir et al (1984) developed an ISD and successfully tested it in evaporation experiments. Comparisons of the performance of the dryer with the other commonly used devices namely, spray dryer, spouted bed, stream dryer, and fluidized bed, have indicated a higher efficiency in carrying out the drying process of moistened particles in an ISD.…”

In this study two simple mathematical models are proposed to describe the drying process of wet particles in a coaxial impinging stream dryer. The models represent the particles in two conditions, surface and internal moisture, which are solved numerically. The effect of various parameters including particle diameter, air velocity, and air temperature are investigated on the final moisture content of the product. In addition, drying intensity of the coaxial impinging stream dryer is compared with the other common dryers. This comparison leads to the conclusion of the high efficiency of impinging stream dryers at higher air velocity and smaller particles. Comparing the results of the models with available experimental data shows that the numerical predications are in good agreement with the experimental ones.
