Experimental heat transfer of rib roughened square, rectangular and trapezoidal cooling channels
This paper explores the heat transfer benefit of using turbulators within turbine airfoil cooling passages. The local and average heat transfer coefficients were measured in scaled models with trapezoidal, square and rectangular cross-section channels with aspect ratios of 0.15, 1, and 3 respectivel...
