Abstract Scope |
High heat flux environments, like those of atmospheric re-entry and fusion reactors, impose severe thermal gradients and high local temperatures. These conditions demand materials with exceptional thermal and structural durability. A scalable heat transfer method, such as transpiration cooling, can be integrated to manage these extreme heatloads. The employment of additive manufacturing (AM) enables fabrication of highly customized structures for optimal heat transfer. In this talk, transpiration cooling of a porous metallic AM architecture with a liquid water coolant will be presented as an effective means to disperse localized heat and maintain structural durability. A high heat flux testing facility, featuring a high powered laser, was developed to characterize structure cooling performance under extreme heatloads. The resulting thermal and oxidation behavior of the structure under these conditions will be discussed. Such tests provide insight to further tailoring the cooling efficiency and mechanical properties of these structures. |
