Implementation of heat pipes for gas turbine cooling

Tarasov A., Litvinenko O.

Prace Naukowe Politechniki Warszawskiej. Mechanika

2003

z. 202

283--290

Numerical solution of boiling and condensation of liquid metal heat carier in porous reservoir was developed to evaluate system capacity to transfer heat flux of high value. It`s ability to transfer heat flux of 10(5)-10(6) W/m.K on distance about 20 mm was proved. The smoothing thermal loading on das turbine blade by means of heat sodium of special type was shown.

280-286

There are numerous methods of calculation heat exchanger of different types. However all of them based on general considering heat exchanger as unit and do not avoid disclosing the heat transfer in detail. The new way based on the graph theory avoids more carefully predicting process in heat exchanger and creating advanced its design. The new way has advantages especially in complicated scheme of heat carrier streams, for instant, when cross flow of carriers take place. Here the heat transfer surfaces should be determined more correctly in comparison with previous ways.

The investigation of the possibility of using the heat pipe for gas turbine nozzle vane cooling was considered. To provide a safe run of gas unit the temperature level of gas turbine parts should be approximately equal to 850-950°C. The high temperature heat pipes with Iiquid-metal heat carrier cover these ones. The problems of numerical prediction of the heat transfer by means of heat pipe are considered.
