Flow structure around and heat transfer from cylinders modified from square to circular
This work aims at numerically investigating the influence of corner modification on the flow
structure around and heat transfer from a square cylinder at a Reynolds number Re= 150
based on the cylinder width d and freestream velocity. The sharp corners of the square
cylinder are rounded with r/d= 0 (square), 0.125, 0.25, 0.375, and 0.5 (circular), where r is
the radius of the corner. The rounded corners have a profound effect on the flow structure
from the perspective of flow separation, vortex strength, separation bubble, and wake bubble …
