Abstract：

Based　on　NACA　airfoil　profile　and　the　structure　of　beveled　vortice　generator,　a　novel　beveled　design　of　NACA　pin-fin　and　its　configuration　in　the　cooling　channel　of　turbine　blade　were　proposed.　Numerical　simulation　was　conducted　to　investigate　the　flow　and　heat　transfer　characteristics　of　this　pin-fin　arrays　in　the　cooling　channel.　The　detailed　physical　field　distributions　of　the　flow　and　heat　transfer　were　discussed　and　the　overall　thermal　performance　was　also　explored.　The　result　indicated　that　the　bevel　cut　of　the　pin-fin　can　produce　lasting　and　stable　longitudinal　vortices　to　strengthen　the　disturbance　of　flow　field,　yielding　a　good　effect　on　enhancing　heat　transfer　of　the　cooling　channel.　©　2021,　Editorial　Department　of　Journal　of　Aerospace　Power.　All　right　reserved.
