Thermal behavior in a 180-deg turned channel with the perforation divider under rotational condition

Fluid Flow and Heat Transfer Charateristics in a 180-deg Round Turned Channel with a Perforated Divider

“…Leading coolant into the internal passages of the blade is widely used in the power machine design. Jeng et al [1]- [3] proposed the configuration of intermediate divider with multiple perforations in the 180-deg turned channel. The coolant in the first duct entered the second duct ahead of time through perforations due to the bypass effect, so that the temperatures of upstream and downstream hot wall surfaces were relatively consistent, to avoid local high temperature at the wall surface of downstream channel.…”
