... in the cross-section of the annuli). Hence, it creates a better hole cleaning situation. The cause of enhanced turbulence production over the Bed 2 can be due to several factors; the primary cause is the bed height. Bed 2 occupies the entire narrow side of the annulus, hence pro- moting a higher velocity over...
