“…However, the connection between VAM and other methods widely used in single-phase fluid mechanics is rarely identified. This section covers volume averaging the governing equations of ablative TPS materials in a manner that demonstrates the relations between VAM (Whitaker 1999), the immersed boundary method (IBM) (Peskin 1972, Goldstein et al 2005, Mittal & Iaccarino 2005, and the large-eddy simulation (LES) method (Leonard 1975).…”

“…The governing equations for the extended dependent variables, q p , are derived by multiplying the governing equations and their boundary conditions in each phase by (γ p ) n , using differentiation by part and properties of the phase-mask. This will yield the extended governing equations derived by Sirovich (1967Sirovich ( , 1968) that are the basis of the IBM (Peskin 1972, Goldstein et al 2005, Mittal & Iaccarino 2005.…”

Ablative thermal protection systems have experienced renewed interest in the past decade owing to the retirement of NASA's Space Shuttle fleet and the US presidential mandate to develop technologies that enable humans to explore space beyond low Earth orbit. Blunt body architecture for spacecraft and the use of ablators for thermal protection systems returned as the primary choice in mission planning. This review addresses current progress in modernizing predictive tools for ablative material response. Current theory development leverages progress made in the theory of flows in porous media. This development, combined with progress in experimental techniques and high-end computing, is enabling the development of 3D macroscale models with realistic closure coefficients derived from direct numerical simulations of 3D microscale geometries of actual materials. While flight data quantifying ablative material response remain sparse, the next decade will be one of exploration in which heatshield instrumented spacecraft will provide crucial flight data for refining and validating closure models.

“…While compared with the traditional phenolic foaming materials, the phenolic cryogel materials prepared by freeze-drying method make its brittleness and powder dropping rate decrease because of its three-dimensional reticular structure [7,8]. What's more, in the process of heat transfer, heat conduction is seriously blocked for its low solids content in unit volume, thermal convection and radiation are badly weakened and obstructed due to its large amount of nano-sized holes which lead to better performance of the thermal insulation [9][10][11][12]. Therefore, phenolic cryogel materials have higher application value than the traditional phenolic foam materials, however, the former also has shortcomings of poor mechanical properties.…”

Phenolic cryogel plates (PCPs) and three-dimensional braided glass fiber reinforced phenolic cryogel composite plates (PCCPs) were successfully fabricated by microemulsion-templated sol gel polymerization and freeze-drying methods. Then, pore morphology, mechanical and thermal properties of the composites were investigated. The experimental results showed that the aerogels made by freeze-drying method had the best microstructure. In addition, it was discovered that the compressive and tensile strength of the cryogel plates had equally increased for approximately 8 and 30 times after compounding with glass fiber. Simultaneously, the mechanical properties of the 20 wt% and 25% solid content (PCPs) achieved the optimal value compared with PCPs of other contents. Moreover, it was found that the cryogels had excellent thermostability, and their thermal conductivity decreased with the reducing of the solid contents, what's more, the joining of glass fiber had the increased the composites’ thermal conductivity to some degree. Finally, considering the requirement of low density, good mechanical and thermal performance, the 20 wt% solid content PCCP had the best comprehensive performance compared with others.
