In this study, we propose novel hybrid square-circular cyclone variants that take advantage of both square and circular cyclones. A total of five cyclone models are analyzed – a square cyclone (baseline model), two cyclone separators having a cylindrical segment over the top with the square section in the remaining part, and the two cyclone models having square segment over the top with a cylindrical section in the lower part. The performance of hybrid cyclones is evaluated using numerical simulations. Apart from mean as well as fluctuating pressure and velocity field, we closely examine the vortex core in both square cyclone and proposed hybrid cyclone geometries. With the proposed hybrid cyclone geometries, it is possible to have a flow field with or without the vortex core – this is a unique way of making selection. Furthermore, the enhancement in performance of hybrid cyclones is significant compared to the baseline model.

在这项研究中，我们提出了利用方形和圆形旋风器的新型混合方形-圆形旋风器变体。一共分析了五个旋风模型——一个方形旋风（基线模型），两个旋风分离器顶部有一个圆柱段，其余部分为方形截面，两个旋流器模型在顶部有方形段和一个圆柱体。下半部分。混合气旋的性能使用数值模拟进行评估。除了平均以及波动的压力和速度场外，我们仔细检查了方形气旋和提出的混合气旋几何结构中的涡核。使用提议的混合旋风几何形状，可以有一个带或不带涡核的流场——这是一种独特的选择方式。此外，
