The local open channels play a certain role in regulating and storing water, but the water flow in the junction section with open channel variation and pressure is relatively complex, which may cause adverse water flow phenomena such as air intake, whirlpool and surges. In order to study the hydraulic pattern of the connecting section between the open channel and the pressurized tunnel, based on the water conveyance tunnel of Wenzhou Oujiang water diversion project, a 30:1 large scale normal local hydraulic model was built according to the gravity similarity criterion. The hydraulic pattern, water surface line distribution, velocity distribution and wave characteristics under different conditions were observed through hydraulic model tests. The flow trend, depth, velocity and wave characteristic parameters under different working conditions were obtained. The research results show that the flow in the open channel and the pressurized junction section through the gradual transition is in good shape, and there is no air intake, backflow and surge, which provides support for the safe operation of the project.

无压渠道具有一定的调蓄作用,但无压变有压的衔接段局部水流相对复杂,可能形成吸气、漩涡和涌浪等不利水流现象。为研究无压隧洞下游与有压隧洞衔接段的水流形态,以温州市瓯江引水工程输水隧洞为例,根据重力相似准则搭建了30∶1的大比尺正态局部水工模型,通过观测不同工况下的过流形态、水面线分布、流速分布和波浪特性,获得了不同工况下水流的流动趋势、水深、流速和波浪特征参数。研究结果表明,通过渐变过渡的无压与有压衔接段的水流形态良好,无吸气、回流和涌浪发生,为工程的安全运行提供了支撑。

无压渠道具有一定的调蓄作用,但无压变有压的衔接段局部水流相对复杂,可能形成吸气、漩涡和涌浪等不利水流现象。为研究无压隧洞下游与有压隧洞衔接段的水流形态,以温州市瓯江引水工程输水隧洞为例,根据重力相似准则搭建了30∶1的大比尺正态局部水工模型,通过观测不同工况下的过流形态、水面线分布、流速分布和波浪特性,获得了不同工况下水流的流动趋势、水深、流速和波浪特征参数。研究结果表明,通过渐变过渡的无压与有压衔接段的水流形态良好,无吸气、回流和涌浪发生,为工程的安全运行提供了支撑。

The local open channels play a certain role in regulating and storing water, but the water flow in the junction section with open channel variation and pressure is relatively complex, which may cause adverse water flow phenomena such as air intake, whirlpool and surges. In order to study the hydraulic pattern of the connecting section between the open channel and the pressurized tunnel, based on the water conveyance tunnel of Wenzhou Oujiang water diversion project, a 30:1 large scale normal local hydraulic model was built according to the gravity similarity criterion. The hydraulic pattern, water surface line distribution, velocity distribution and wave characteristics under different conditions were observed through hydraulic model tests. The flow trend, depth, velocity and wave characteristic parameters under different working conditions were obtained. The research results show that the flow in the open channel and the pressurized junction section through the gradual transition is in good shape, and there is no air intake, backflow and surge, which provides support for the safe operation of the project.
