We investigate the frictional force which is acting on a pipeline pig. Two complementary experimental setups have been designed and used to study the sealing disc of a pig, which is responsible for the frictional force between the pig and the pipe wall. Six 12’’ off ...
We present experimental and numerical results for by-pass pigging under low-pressure conditions which aided the design of a speed-controlled pig (Pipeline Inspection Gauge). Our study was carried out using air as working fluid at atmospheric pressure in a 52 mm diameter pipe o ...
One-dimensional models for multiphase flow in pipelines are commonly discretised using first-order Finite Volume (FV) schemes, often combined with implicit time-integration methods. While robust, these methods introduce much numerical diffusion depending on the number of grid ...
In the oil and gas industry, bypass pigs are used to allow part of the production fluids to bypass the pig (Pipeline Inspection Gauge) during a pigging operation as compared to a conventional pig. This has been proven to be beneficial for both cleaning of the pipe and inspecti ...
