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.
