Wheeled Capsule Threshold of Motion at Different Locations in a Horizontal Bend Pipeline Based on Hydraulic Capsule Pipeline Transportation

As the process before transporting of capsule in a hydraulic pipeline system, capsule’s threshold motion is often tested horizontal straight pipe. However, result physical test this work shows that wheeled more easily start-moves bent Thus, numerical simulation and theory analysis were used to study The results demonstrate velocity magnitude water flow was asymmetric between inner part outer section closing on capsule. This unlike From result, new mechanical model proposed divides into two parts. parts correspond section. Then, deduction has shown bolsters pipe endured lower maximum static friction than those whole unstable because additional drag force induced by centrifugal effect pipe’s flow.
