Мақолада циклон кириш қисмидаги чанг оқимининг тезлиги циклонларнинг ишлашига таъсири ўрганилган. Оқим майдони структураси Рейнольдснинг турбулентлик (МТНР) модели ёрдамида ҳисоб-китоблар орқали кўриб чиқилди. Натижалар шуни кўрсатадики, циклондаги максимал тангенциал тезлик циклонга кириш ҳажми ошиши билан камаяди. Циклон фазосида тезланиш содир бўлмайди (максимал тангенциал тезлик бутун циклон бўйлаб деярли доимий). Циклонга чанг кириш ҳажмини ошириш босимнинг пасайишини камайтиради. Циклоннинг диаметри унинг кириш қисми ўлчами билан ортади (шунинг учун уюрма кучи туфайли циклоннинг ФИК пасаяди). Кириш кенглигини ўзгартиришнинг таъсири кириш баландлигидан кўра муҳимроқ ҳисобланади. Тезлик тебраниши симуляция қилишнинг циклон сепараторлари самарадорлиги ошишига таъсири (МТНР) ва катта гирдоб симуляцияси (МБВ) ёрдамида рақамли ўрганилди. Эйлер-Лагранж моделлаштириш ёндашуви Solidworks Flow Simulation томонидан юқори самарали Старманд циклонида 3D стационар бўлмаган турбулент газ ва қаттиқ оқимларни симуляция қилиш учун ишлатилган. Симуляция натижалари мавжуд адабиёт маълумотлари билан солиштирилди. Натижалар таҳлили шуни кўрсатадики, МТНР ва МБВ ўртача оқим майдонини етарли даражада аниқлади. Шунингдек, МБВ ҳар бир заррача ўлчами учун ўзгарувчан оқим майдони ва ушлаш самарадорлигини прогноз қилишда яхши натижалар кўрсатди. Циклонларда тезлик тебранишларини моделлаштириш ҳам ушлаш самарадорлиги прогнозида, айниқса, кичик зарралар учун катта таъсир кўрсатади.
