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. The Reynolds number is kept at 250,000 and both on- and off-design conditions are tested. For the on-design condition where the incidence angle of OGVs is 30°, no obvious flow separation phenomenon was observed; on the contrary, for the off-design conditions where the incidence angle of OGVs is 0° and −31°, respectively, remarkable flow separation was noticed. The results indicate that the incidence angle of OGVs has a significant effect on the endwall heat transfer. In general, the endwall heat transfer coefficients for the off-design conditions are higher than the corresponding on-design condition. In addition, a preliminary CFD analysis was performed and presented. Basically, the results are consistent with the experiments but further investigations are needed in the future work.
