Aerothermodynamic study of UHTC-based thermal protection systems

Plasma wind tunnel testing of ultra-high temperature ZrB2–SiC composites under hypersonic re-entry conditions

“…27 The computations were carried out by using the commercial FLUENT package 28 with ad hoc userdefined-functions developed in house to take into account the change of the surface temperature during the test and the radiation emitted from the surface at relatively high temperature. The thermophysical properties of the UHTC material used in this work were previously measured.…”

Material property requirements for analysis and design of UHTC components in hypersonic applications

“…24 Requirements for the level of coupling to achieve time-accurate solutions for UHTC components are discussed in the literature. 24,29,30 …”

A low risk reentry: looking backward to step forward

“…Steady-state simulations are performed by a pseudo-time integration algorithm based on an explicit fivestage Runge-Kutta scheme. A more detailed description of the numerical technique may be found in [12,18]. A sketch of the computational grid is shown in Fig.…”
