Abstract
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◦ with inline arrangement while it has been achieved by angle-22.5◦ with staggered arrangement. On the other hand, the maximum friction
factor with both inline and staggered arrangements is represented by angle-0◦. The highest thermohydraulic performance has been achieved by angle-22.5◦ 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.
