Cfd simulation of annular flows through bends
WebThe granular temperature of cuttings is high near the wall of drill pipes, which indicates that the energy from the rotating drill pipe is transferred to cuttings. Effects of three rheological parameters (τ 0, K HB and n) on the flow behavior of cuttings and H B fluid were analyzed. With the increase of Herschel-Bulkley fluid rheological ... WebNov 1, 2010 · The CFD software FLUENT 6.3.26 [1] is used to model core annular downflow through a 0.012 m diameter tube with lube oil as core and water as the annular fluid. The model is validated with experimental results obtained by the authors on pressure drop and core thickness. It is then used to generate useful data regarding the …
