Abstarct: Gas turbines are one of the main sources of electricity in the world. Researchers have always been interested in increasing productivity and efficiency. one of the ways to increase the efficiency of gas turbines is to increase the temperature of combustion products entering the turbines, but due to some considerations related to the material and melting temperature of moving and fixed parts of the turbine, this temperature increase is limited. One of the common methods to increase the temperature of combustion products Entrance to the turbine is the cooling of fixed and moving blades. In this regard, this study tries to increase the temperature of inlet combustion products by internal cooling method of moving blades. Provide turbine and thus increase the thermal efficiency of the turbine. The focus of this research is on cooling the end area of the moving turbine blade, where due to the inevitable leakage of combustion products due to the pressure difference between the high pressure front and low pressure area, is a critical area in terms of thermal loading. For internal cooling of this part of the blade, a cooling flow is passed through the spiral channels embedded inside the blades , this flow causes cooling by receiving heat from the body of the blade. To increase the heat transfer coefficient and Nusselt in the blades, we use heat transfer amplifiers such as pinfins, dimples and proturtions. These amplifiers improve heat transfer by increasing the heat transfer surface as well as increasing the turbulence parameters of the fluid flow. To simulate the complex turbulence behaviors of the three-dimensional fluid flow, Fluent software is used in the Reynolds range of 100,000 to 400,000. According to the results, the use of turboulators and thermal amplifiers increase heat transfer by almost 2.7 times compared to the channel mode without amplifier, while the pressure drop caused by these amplifiers is almost ten percent more
