Dissolved oxygen (DO) is a vital nutrient for the health of water bodies such as streams, rivers, and ponds, as it is used in respiration and other biological activity of aquatic animals. Natural replenishment of oxygen through photosynthesis in aquatic bodies is insufficient to meet the high requirements for an intensive aquaculture system, which compels farmers to use aeration systems to supplement the natural process of DO accumulation. When the demand for oxygen (KgO₂/h) is lower, venturi aerators may be more effective than other aerators. The venturi device is an aeration system which is highly efficient in providing an adequate supply of DO, and is flexible in nature and easy to operate. To evaluate the efficacy of air entrainment holes on the throat of a venturi, aeration experiments were conducted for different throat lengths (L_t) of 20, 40, 60, 80 and 100 mm, varying the number of air holes according to throat length while maintaining a constant air hole diameter of 2 mm. Aeration efficiency was found to increase with an increasing number of air holes. The highest oxygen transfer coefficients for throat lengths of 20, 40, 60, 80 and 100 mm were 0.497 h⁻¹, 0.756 h⁻¹, 1.045 h⁻¹, 0.627 h⁻¹ and 1.072 h⁻¹, respectively, with the maximum number of air holes (NH). The maximum standard aeration efficiency was found to be 1.25 × 10⁻² kgO₂/kWh for a throat length of 100 mm with the maximum number of air holes (NH₁₇). Hence, the physical properties of throat length, number of air holes, and distribution of air holes on the throat section were proven to be key factors controlling the performance of the venturi aeration system.

溶解氧（DO）是用于水流，河流和池塘等水域健康的重要营养素，因为它被用于呼吸和水生动物的其他生物活动。通过水体中的光合作用自然补充氧气不足以满足集约化水产养殖系统的高要求，这迫使农民使用通气系统补充溶解氧的自然过程。当需氧量（KgO ₂/ h）较低，文丘里曝气器可能比其他曝气器更有效。文丘里管装置是一种曝气系统，在提供充足的DO方面非常高效，并且性质灵活且易于操作。为了评估引气孔在文丘里喉管上的功效，针对20、40、60、80和100 mm的不同喉管长度（L _t）进行了通气实验，并根据喉管长度改变了气孔的数量。保持2 mm的恒定气孔直径。发现通风效率随着气孔数量的增加而增加。用于咽喉长度最高氧传递系数20，40，60，80和100 mm们0.497ħ ^-1，0.756ħ ^-1，1.045ħ ^-1，0.627ħ^-1和1.072 h ^-1分别具有最大数量的气孔（NH）。发现在最大气孔数（NH ₁₇）的情况下，喉长为100 mm时，最大标准曝气效率为1.25×10 ^-2 kgO ₂ / kWh 。因此，事实证明，喉管长度，气孔数量以及气孔在喉管部分的分布等物理特性是控制文丘里通风系统性能的关键因素。
