    The cooling fluid deflects to one side due to the turbine blade rotating. And it induces the uneven cooling
    performance on the turbine blade. As a result, utilizing this rotational effect to achieve improved cooling on each side
    is one of the good strategies for improving the performance of internal cooling flow. In the internal flow path of a
    conventional turbine blade, the flow flows in a radial direction, and thus it is difficult to improve the cooling
    performance using the rotational effect. In order to overcome these disadvantages, the rotational direction of the
    cooling fluid in the inner flow path is changed from the pressure side to the suction side or the suction side to the
    pressure side to improve the cooling performance utilizing the rotational force. Computational analysis was
    performed for this purpose. As a result, it was confirmed that the cooling performance was improved by the rotation
    effect. In addition, an additional impact jet cooling or bypass flow path was made on the inner wall of the turbine
    blade to study the improvement of cooling performance to reduce the pressure drop.
