Experimental study of cooling efficiency of film cooling with tab;

Investigation of the wall temperature distribution and cooling efficiency for impingement/effusion cooling scheme;

Study of overall cooling effectiveness of discrete holes with different angles to concave wall;

Detailed heat transfer and full coverage film cooling measurements were conducted on the turbine blade surface,primarily research the effect of different reynolds number and mass flow ratio on local heat transfer and film cooling effectiveness.

To investigate the influence of the hole shape on the film cooling effectiveness of the maze composition structure of a combustor,a numerical study on the distribution of its wall temperature and cooling effectiveness was performed when the outside wall holes were dust-pan shaped holes,cone shaped holes and round holes.

Adiabatic effectiveness measurements on rotating curvature models

The results show that the effect of the rotation number is obvious:deflection angles are improved with the increasing rotation numbers;the augmentation of Rt results in decreased adiabatic effectiveness for convex surfaces,while for concave surfaces,increasing Rt leads to improved adiabatic effectiveness.

Computations were performed to investigate the adiabatic effectiveness η distributions on the curvature turbine blade models under rotating conditions.
