Figure 9. Pathlines colored by non-dimensional spanwise velocity for a flat temperature profile and 2% coolant mass flow from the slot.

Figure 10a-b. Endwall film-cooling predictions for a case with a flat temperature profile. These predictions include endwall adiabatic effectiveness levels, (a) and vane effectiveness levels along the suction side (b).
Figure 10c-d. Endwall film-cooling predictions for a case with a flat temperature profile and 1% slot cooling. These predictions include streamline pattern in the near-wall region colored by the spanwise velocity component.
Figure 11. Temperature profiles for the hot-streak with a single heater on. Distances measured downstream of the heater. Positions x/C = 0.77 and 1.38 are upstream of the vane, and x/C = 3.0 is downstream of the vane.
