Monitoring and analysis of cooling effect of block-stone embankment for Qinghai-Tibet Railway;

It has been proven that the structure of machine,the cooling effect ,the quality of cooling substance and the working noise,etc.

,the factors affecting cooling effect are analyzed in detail according to the principles of heat conduction,convection,radiation and the measures to improve cooling effect are put forward,such as improving sealing to reduce leakage,improving the ore distribution to restrain edge effect,and increasing layer height etc , which are very helpful to improve cooling efficienc

Influence of aerodynamic parameter on the temperature gradient and cooling efficiency for effusion wall cooling method;

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.

Numerical simulation on the cooling effect of water sprinkler on hot smoke;
