摘要：

The current study represents a numerical investigation of the pin fin heat sink performance with different angles of wings. Five angles ranging from 0 degrees to 90 degrees have been represented and studied under inline and staggered arrangements of pin fins. Reynolds numbers range from 13,500 to 37500. The highest Nusselt number has been achieved by angle-0 degrees with inline arrangement while it has been achieved by angle-22.5 degrees with staggered arrangement. On the other hand, the maximum friction factor with both inline and staggered arrangements is represented by angle-0 degrees. The highest thermohydraulic performance has been achieved by angle-22.5 degrees for staggered arrangement while case without wings gives the highest performance for inline arrangement. Using wings in staggered arrangement shows significant effect on heat transfer performance. While it is not recommended to use wings in case of inline arrangement.
