Multiblock analysis for Shuttle Orbiter reentry heating from Mach 24 to Mach 12

摘要: A multiblock, laminar heating analysis for the shuttle orbiter at three trajectory points ranging from Mach 24.3 to 12.86 on re-entry is described. The performed using Langley Aerothermodynamic Upwind Relaxation Algorithm (LAURA) with both a seven species chemical nonequilibrium model and an equilibrium model. finite-catalytic-wall appropriate tiles radiative wall temperature applied. Computed levels are generally in good agreement flight data though few rather large discrepancies remain unexplained. multiblock relaxation strategy partitions flowfield into manageable blocks requiring fraction of computational resources (time memory) required by full domain approach. In hot, cost solution even single point would be prohibitively expensive given resolution without Converged reassembled enable fully coupled converged over entire vehicle, starting nearly initial condition.
