摘要:
对喷雾干燥过程中旋风分离器工作过程及其分离原理做了简要介绍,给出了旋风分离器内三维流场以及颗粒轨道的数学模型,运用雷诺应力模型(RSM)对其进行了三维数值模拟.数值模拟得到了旋风分离器内三维气体流场以及颗粒的运动轨迹,获得了旋风分离器在不同进口风速下的进出口压降和不同粒径下的分离效率.模拟计算结果可供旋风分离器设计及应用提供一定的参考.
Abstract:
The working pro cesses and pr inc iples of cy clone separator w ere introduced in th is paper. The m athem atical m ode ls of the three-dim ens iona l flow fie lds and tra jectory of particles in cyclone separators were established. The Reyno lds StressM ode l( RSM ) w as used to com pute the fie ld. The three-dim ens iona l flow fie lds and tra jec to ry o f partic les w ere obta ined by num er ica l s imu la tion. The d ifferen tia l pressures between in let and outle t o f cyc lone separator under d i-f ferent inlet a ir v elocities and separa tive effic iencies and diffe rent par tic le diam ete rs w ere also obta ined by num er ica l ca-l culation. The results can prov ide a re ference for des igning and applica tions of cyc lone sepa ra to r.
