Scaling of overall cooling effectiveness of HPT NGVs from conventional laboratory conditions to engine conditions

Thesis

The increased use of engine-realistic test vehicles in turbomachinery research has contributed to practical and academic interest in a robust validated theory for the scaling of overall cooling effectiveness (θ) from conventional laboratory conditions to engine conditions. The purpose of this thesis is to quantify and explain the effect of moving from conventional laboratory conditions to engine conditions on θ, via theoretical considerations and experimental validation.<...
