Abstract Improved film cooling hole geometries and effect of coolant density on film cooling have been a focus since the 1970s. One of the first studies on
modifying hole exit to improve film cooling effectiveness and quantifying coolant density effect was from Prof. Goldstein’s group. This paper provides
an overview of the development and implementation of hole exit geometries as well as coolant density study over the past few decades and the impact
on future studies of advanced hole geometries under realistic engine-like coolant-to-mainstream density ratio conditions. This work is not intended to
be a comprehensive More >
