The growth of the Brazilian economy has resulted in an increased demand for engineers and the expansion of Brazilian Universities. As for the teaching of unit operations, a lack of interactive and illustrative courseware was observed. The modeling and simulation tools are excellent alternatives to predict the particle and fluid dynamics and have been used in the design and optimization of industry equipment, providing information in areas where it is difficult to acquire experimental measurements. This paper shows simulations using the computational fluid dynamics technique of the exercises presented in a course on solid–fluid separation in the gravitational field, such as sand chambers, dust chamber, horizontal and vertical elutriators. The effect of size, shape, and density of particles on the collection efficiency was evaluated. Figures and videos generated in this study will facilitate students' understanding of the phenomena involved in the particle collection inside those separation devices.

重力场中的固液分离：使用计算流体动力学模拟生成课件

巴西经济的增长导致对工程师的需求增加和巴西大学的扩张。至于单元操作的教学，则发现缺乏互动性和说明性的课件。建模和仿真工具是预测粒子和流体动力学的绝佳替代品，已用于工业设备的设计和优化，为难以获得实验测量值的领域提供信息。本文展示了使用计算流体动力学技术对重力场中固液分离课程中的练习进行的模拟，例如沙室、集尘室、水平和垂直淘析器。评估了颗粒的大小、形状和密度对收集效率的影响。
