A CFD- RSM study of cuttings transport in non-Newtonian drilling fluids: Impact of operational parameters by Abdelrahman M. Awad (16932519)

“…Less effective cuttings transportation (i.e lower CTR) was observed when the hole angle deviated from the vertical. In addition, a significantly higher CVT (up to 73%) was recorded for eccentric pipes as compared to the concentric cases, primarily due to the reduced fluid velocity in the narrow gap of the eccentric annulus. …”
