  • SEMI-PASSIVE COOLING USING HIERARCHICAL VASCULATURE
    Publication number: 20220074639
    Abstract: A semi-passive cooling system for a component exposed to a fluid flow utilizes a hierarchical vasculature and a sacrificial transpirant to cool the component. The component includes a body that defines a transpirant reservoir and the hierarchical vasculature. The transpirant is configured to transition between a solid phase and a vapor phase over an operating temperature range of the component.
