PERFORMANCE OF ZIGZAG CLASSIFIERS AT LOW PARTICLE CONCENTRA TIONS: A study of the Effect of Stage Geometry Variations
نویسنده
چکیده
In the case of zigzag air classifier of standard depth the channel depth dt is fixed by the section length Ls and the angle between the sections a. The channel width Wc remains to be specified. The author chose the square-bottom configuration (JI c = Ls = 20 cm) for three air classifiers investi gated in the paper. An alternative choice is to have Wc inversely proportional to sin a, 0 < a < 180 de gree. The latter choice yields an a-independent re lation between the volume rate of flow of air across a section and the mean air speed there.

In the study, the thermal-hydraulic performance of the zigzag channels with circular cross-section was analyzed by Computational Fluid Dynamics (CFD). The standard K-Ꜫ turbulent scalable wall functions were used for modeling. The wall temperature was assumed constant 353 K and water was used as the working fluid. The zigzag serpentine channels with bend angles of 5 - 45° were studied for turbul...
متن کاملThe effect of wall strengtheners on the performance of double-stage electrostatic precipitators
The presence of wall strengtheners in double-stage electrostatic precipitators affects gas velocity, electrical field and particle movement over the ESP. In this work we have used our previous mathematical model for double-stage ESP {Talaie et. al (2001) [10]] to study the effect of wall strengtheners on the performance of double-stage ESP. One of the important findings was that, due to the fac...

متن کاملInvestigation of the effect of amount and size of gypsum particles on its performance in the improvement of saline and sodium soils
Extended abstract 1- Introduction Gypsum, sulfuric acid, and sulfur are used to improve saline and sodic soils. In some cases, animal manures are also used, which varies according to environmental conditions and soil type (Jesus et al., 2019). Industrial gypsum is often used to modify saline and sodic soils due to electrolyte maintenance, physical and hydraulic properties (Keren, 1996), low c...
