The effect of the installation of a cutting pin in front of a cylindrical rod was analyzed. Different cutting pin heights were compared through numerical simulations. The numerical simulations were conducted using ANSYS CFX (Ver. 17.2). The cutting pin heights were hp/H = 0.25, 0.5, and 0.75. The results revealed that the cutting pin with hp/H = 0.25 increased the strength of the horseshoe vortex, which occurred at the leading edge of the cylindrical rod. Therefore, the heat transfer distributions between the cutting pin and the cylindrical rod increased. Moreover, the area-averaged heat transfer distributions increased to up to a factor of 22 % when the cutting pin was installed. Therefore, choosing an appropriate height for the cutting pin will be helpful when it is installed in front of the pin-fin array of the internal passage of a gas turbine blade.
