Experimental Study of Endwall Heat Transfer in a Linear Cascade
(2012) 6th European Thermal Sciences Conference (Eurotherm) 395. p.012028-012028- Abstract
- The endwall heat transfer characteristics of forced flow past outlet guide vanes (OGVs) in a linear cascade have been investigated by using a liquid crystal thermography (LCT) method. Due to the special design of an OGV profile, the focus of this study is emphasized on the heat transfer patterns around the leading part of a vane. The Reynolds number is kept constant at 260,000. Two attack angles of the vane are considered. For alpha = 0 degrees, the vane obstructs the incident flow like a bluff body and a remarkable flow separation phenomenon was noticed. For alpha = 30 degrees, the vane is more "streamlined" with respect to the incoming flow and no obvious flow separation was observed. In general, the endwall heat transfer for alpha = 0... (More)
