Modern gas turbine efficiency is improved by active cooling of the turbine blade trailing edge. The research seeks to improve turbine efficiency by increasing the cooling performance. For some time, pin fins have been used as the most common means of heat transfer enhancement. Among different types of pin fins, circular cross-section or cylindrical pin fins are the most popular and studied pin fins. A state-of-the-art design passes cooling air through a high-solidity pin array in a cavity in the trailing edge. A novel configuration with split cylindrical pin fins in which each pin has a centered slot in the mean flow direction are considered in this study. Computational simulations of flow with the proposed design reveal a significant improvement in cooling ability as compared to the currently used solid pin arrays.
