Grahic Jump Location
The internal coolant passage test facility and turn region details
Grahic Jump Location
Measurement sections. The symbols represent the measurement lines (Y direction) that will be analyzed in the next sections (Figs. 5 and 6).
Grahic Jump Location
Hole velocity profile and remaining bulk massflow along the hole configuration centerline
Grahic Jump Location
Mean streamwise velocity contours and secondary flow vectors obtained at θ=0, 45, 90, 135, and 180 deg in the bend. The contour lines values, Uθ, are plotted on the figures (Uθ/Ub).
Grahic Jump Location
Streamwise velocity contours immediately downstream of the bend, 0.0<X<4.0 at three distances from the bottom wall (U/Ub)
Grahic Jump Location
Centerline velocity profiles differences (baseline-hole), normalized by Ub. {a: Streamwise velocity: U; b: radial velocity (from the web toward the outer walls, i.e. 1:along Z-axis: W; 2: along r-axis: Ur; 3:along Z-axis:-W); c: vertical velocity along Y-axis: V;} (e.g., Fig. 2 for exact locations in the rib modules).
