Abstract

IN RECENT YEARS, THE FIELD OF COMPUTATIONAL FLUID DYNAMICS (CFD) HAS WITNESSED SIGNIFICANT ADVANCEMENTS, PARTICULARLY IN ITS APPLICATIONS FOR SIMULATING AND ANALYZING INDUSTRIAL FLOWS. AMONG THESE APPLICATIONS, THE STUDY OF CYCLONE SEPARATORS STANDS OUT FOR ITS CRUCIAL ROLE IN THE STEEL INDUSTRY, WHERE SUCH EQUIPMENT PLAYS A VITAL ROLE IN ENVIRONMENTAL POLLUTION CONTROL AND COST REDUCTION. WHILE PREVIOUS RESEARCH HAS EXTENSIVELY EXAMINED THE IMPACT OF VORTEX FINDER DIMENSIONS ON TANGENTIAL CYCLONES, THE SAME LEVEL OF INVESTIGATION FOR AXIAL CYCLONES REMAINS LESS DEVELOPED. MOREOVER, PRIOR TO THIS STUDY, THERE WAS A LACK OF UNDERSTANDING REGARDING THE EROSION FIELDS GENERATED BY THE SWIRLING SEPARATED MATERIAL DOWNSTREAM FROM THE EQUIPMENT UNDER SCRUTINY. TO ADDRESS THESE KNOWLEDGE GAPS, THIS STUDY EMPLOYS A TWO-STAGE CFD APPROACH, AIMING TO NOT ONLY FILL THESE VOIDS BUT ALSO PROPOSE GEOMETRY ALTERATIONS TO ENHANCE CYCLONE OPERATION.
