Review of Passive Cooling Techniques in Gas Turbine Blades to Enhance the Heat Transfer Rate
Author(s): Sushil Sunil Gaikwad*
In recent years the gas turbines have become an important part of power generating industries. As the demand of
power is increasing day by day, the generation of additional power requires a gas turbine to produce more amount
of energy per day. In order to achieve this more shaft power needs to be generated per unit time. This means
the turbines should operate at higher temperatures of the gas at the inlet (Turbine Inlet Temperature or TiT)
to increase the power as well as to enhance the efficiency of the gas turbines. But if the temperature is increased
beyond a specific value it may cause the turbine blades to melt and ultimately damage it. In order to prevent this
melting and damage, cooling techniques are employed in the gas turbines. There are mainly two types of cooling
techniques-Active cooling and Passive cooling. Active cooling relies on external cooling d.. View more»
