Public award description

EFFICIENT, MULTI-SCALE RADIATION TRANSPORT MODELING FOCUSING ON A REDUCED-DIMENSION PROBLEM OF A HYPERSONIC ORBITAL/LUNAR REENTRY CAPSULE, AN ALGORITHM WILL BE BUILT WHICH COMBINES THE STOCHASTIC MONTE CARLO METHOD FOR TREATMENT OF RADIATION TRANSPORT IN OPTICALLY THIN TO MODERATE DOMAINS, WITH A SINGLE-TERM MODIFIED DIFFERENTIAL APPROXIMATION (MP1) FOR USE IN OPTICALLY THICK DOMAINS. THIS NUMERICAL METHOD WILL BE VERIFIED AGAINST A KNOWN BENCHMARK CASE BEFORE APPLICATION TO THE REENTRY PROBLEM. THE BANDWISE AND CUMULATIVE DISTRIBUTION FUNCTION (CDF) METHODS WILL BE COMBINED WITHIN THE MONTE CARLO FRAMEWORK, CREATING AN EFFICIENT, DUAL-HYBRID RADIATION TRANSPORT ALGORITHM. A DETAILED PLAN FOR THE GENERATION OF THE FULL ALGORITHM WILL BE DEVELOPED, WITH A FOCUS ON PARALLELIZATION AND COMPATIBILITY WITH EXISTING COMMERCIAL TRANSPORT SOFTWARE. THIS PLAN WILL INCLUDE THOROUGH TESTING AND VALIDATION STAGES.
