The network was found to quickly and accurately replicate the stiffness predicted by the micromechanics model using a 2D image of an idealized representative volume element of a fiber/matrix microstructure. The long-term goal of this work is to efficiently apply multi-scale methods for predicting the damage progression of a composite structure.","PeriodicalId":165313,"journal":{"name":"AIAA Scitech 2021 Forum","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"121331464","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This plasma is produced at local thermodynamic equilibrium at 8000 K and 1 atm by a 50-kW Inductively Coupled Plasma torch and passes at high-velocity through a water-cooled tube that forces rapid cooling and recombination. The electronic-specific model takes into account NO(C 2 Π) predissociation, spontaneous emission from the C 2 Π and D 2 Σ + states towards the A 2 Σ + state, and quenching of the excited states by various colliders. This model, alongside two other electronic-specific CR models developed for NO at NASA, is compared to measurements of NO excited states and electron densities along the tube length. Better agreement is obtained with the model presented in this work, especially because of the NO(C 2 Π) predissociation and NO C 2 Π and D 2 Σ + spontaneaous emission toward NO(A 2 Σ + ). The electron overpopulation is also explained by the partial equilibrium between N and O atoms and electrons, and the slow depletion of N and O atoms by the NO recombination reactions.","PeriodicalId":165313,"journal":{"name":"AIAA Scitech 2021 Forum","volume":"81 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"116515734","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We are interested in how multiwavelets (MWs) and their properties may shed new light on the adaptation process. This is motivated by the fact that MWs break any input apart into a hierarchy of low resolution data and subsequently finer details. Our error estimator makes use of MWs’ properties while being local to the element, maintaining the parallel efficiency of the solver. Early tests on the one-dimensional viscous Burgers’ equation show promising results. This work will be focused on a backward-facing step configuration to assess the performance of the method in higher dimensions.","PeriodicalId":165313,"journal":{"name":"AIAA Scitech 2021 Forum","volume":"98 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2021-01-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133840133","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
