Аэродинамические исследования циклонов и разработка устройств для снижения их гидравлического сопротивления

n the article results of experimental researches of distribution of gas speeds in an exhaust pipe of the most wide- spread cyclones CN-11 and CN-15 on which basis theoretical calculations by definition of relative losses of the pressure connected with rotation of a gas stream on an exit from an apparatus are carried out are resulted. For such cyclones these losses make accordingly 28,5–30% and 27–28% from the general losses. Two new designs of blade untwisting devices are developed, allowing to reduce power consumption of cyclones and to increase efficiency of cleaning
