Title: | Flow of kaolinite suspension in a sudden expansion | Authors: | Nguyen Luong Khang | Keywords: | Kaolinite;Water kaolinite suspension | Issue Date: | 2023 | Abstract: | Kaolinite, a clay mineral of significance in various industrial contexts, introduces unique challenges to fluid dynamics due to its particulate nature. The investigation centers on unraveling the intricate interplay between the rheological characteristics of kaolinite suspension and the geometric attributes of a sudden expansion channel across a Reynolds number range of 20 to 100. The outcomes of this research contribute to an enhanced comprehension of kaolinite suspension dynamics, offering potential optimizations for industrial processes. In this thesis, a numerical approach is utilized to explore the behavior of a water–kaolinite suspension characterized by varying kaolinite concentrations, specifically 15wt%, 20wt%, and 28.5wt%. The suspension is conceptualized as a Bingham fluid, drawing upon rheological data obtained from existing literature. The chosen Bingham fluid model provides a well-founded basis for simulating the viscoplastic behavior of the suspension, paving the way for a comprehensive understanding of its rheological response across a spectrum of concentrations.The meshing process is carefully undertaken to ensure accuracy and computational efficiency. The simulation tool employed for this investigation is ANSYS Fluent, a widely recognized and extensively utilized computational fluid dynamics (CFD) software. The chosen simulation domain is characterized by a sudden expansion with a geometric ratio of 3, a pivotal aspect influencing the overall flow dynamics |
