Abstract
In this study,cyclonic pneumatic conveying was achieved by installing an additional air intake on sidewall of the conveying pipeline to reduce the energy consumption of pneumatic conveying.The computational particle fluid dynamics(CPFD)approach was employed for numerical simulation.Three auxiliary intake structural parameters(intake velocity,tilt angle,and separation between adjacent auxiliary intakes)and the target value(power consumption coefficient)were subjected to a one-factor hill-climbing test.A multi-group central experiment for multi-objective optimization of three structural parameters was designed using response surface methods.The results indicated that the horizontal pipe pressure drop could be effectively reduced by incorporating an auxiliary intake with an intake velocity of 8m/s,an intake angle of 45°,and an adjacent auxiliary intake distance of 1250mm when the main intake velocity was 13m/s.Compared to systems operating at main intake velocities of 13m/s,15m/s and 17m/s without auxiliary intakes,the power consumption coefficients were reduced by 10.59%,35.36%,and 34.81%,respectively.关键词
