The Two-dimensional Implicit Thermal Response and Ablation program,
TITAN, was developed and integrated with a Navier-Stokes solver,
GIANTS, for multidimensional ablation and shape change simulation
of thermal protection systems in hypersonic flow environments. The
governing equations in both codes are demoralized using the same
finite-volume approximation with a general body-fitted coordinate
system. Time-dependent solutions are achieved by an implicit time
marching technique using Gauess-Siedel line relaxation with
alternating sweeps. As the first part of a code validation study,
this paper compares TITAN-GIANTS predictions with thermal response
and recession data obtained from arc-jet tests recently conducted
in the Interaction Heating Facility (IHF) at NASA Ames Research
Center. The test models are graphite sphere-cones. Graphite was
selected as a test material to minimize the uncertainties from
material properties. Recession and thermal response data were
obtained from two separate arc-jet test series. The first series
was at a heat flux where graphite ablation is mainly due to
sublimation, and the second series was at a relatively low heat
flux where recession is the result of diffusion-controlled
oxidation. Ablation and thermal response solutions for both sets of
conditions, as calculated by TITAN-GIANTS, are presented and
discussed in detail. Predicted shape change and temperature
histories generally agree well with the data obtained from the
arc-jet tests.
