The gas centrifugal separator is widely used due to small size and high efficiency.A new type of gas-liquid separator that combines gravity separation and centrifugal separation is proposed to handle complex and unstable two-phase flows.The outer cylinder structure is optimized through numerical simulation and gas-liquid separation experiments are designed to verify the separation performance of the separator.The results show that as the height ratio of the inner and outer cylinders of the separator increases,the separation efficiency slowly increases,and the pressure drop also increases accordingly.As the ratio of inner and outer cylinder diameters increases,the separation efficiency significantly increases and the pressure drop decreases accordingly.
