Heat Transfer and Flow Characteristics in Rib-/Deflector-Roughened Cooling Channels with Various Configuration Parameters
The present paper deals with a detailed numerical investigation of the turbulent flow inside a stationary rib-/deflector-roughened cooling channel. Various downstream-shaped deflectors including sloping-board deflectors [Cases A1, A2], guide-shaped deflectors [Cases B1, B2], and drop-shaped deflectors [Cases C1, C2] and configuration parameters such as channel aspect ratio (AR=0.5, 1 and 2), and r
