Abstract

The paper presents numerical simulation(two-dimensional) of the averaging pitot tube applied in the pipe with diameter of 300mm.In the calculation the turbulent model of k-ω SST and SIMPLE method were applied.Firstly,the relationship between the flow coefficient and velocity was investigated.Then a two-profile averaging pitot tube was innovatively desingned.The new tubes could offer higher pressure difference and lower flow coefficient at a limited cost on permanent pressure loss compared to the original model.
