Abstract: | As a transport means of oil and gas the submarine pipeline has many merits, such as continuous delivery, large conveying capacity,
convenient management, etc. A tube was chosen in our study to simulate the submarine pipeline in the experiments. A high accuracy instrument ADV and
high precision point-type pressure sensors were used to measure the parameters of the flow field, including the pressure distribution,
velocities at seven cross sections near the submarine pipeline with five different clearance ratios, and twelve dynamic pressure
values around the pipeline. The pressure distributions and velocity changes around the pipe under different flow velocities
and clearance ratios were analyzed. These results might be useful for further study of submarine pipeline erosion and protection. |
