In Phase I, 2D and 3D models of MRES methodology were developed. An acoustic analogy module based on Ffowcs Williams and Hawking technique was developed to accurately propagate the near-field acoustic signals to far field with minimal dissipation and dispersion. An innovative Runge-Kutta temporal update was developed to advance all grid levels independently. The feasibility and accuracy of the MRES technology was demonstrated by predicting noise sources and acoustic waves generated by vortex shedding. The Phase I results indicate that the proposed technology will provide up to two orders-of-magnitude reductions in CPU time over existing techniques.  In Phase II, we propose to improve the 3D MRES software to handle multi-block, curvilinear, viscous and massively parallel applications. An efficient data structure will be developed and implemented to store and update the multiresolution data to improve the cost-saving factor. Unsteady turbulence models based on DES and PANS will be implemented to better resolve the sources of noise. The acoustic module will be improved to account for surface motions and quadrupole source terms. The developed modules will then be coupled to a large-scale CFD code to expand the application base of the technology. The technology will be demonstrated and validated using typical aeroacoustic applications such as Energy Efficient Transport (EET) airfoils and landing gear models.","releaseStatus":"Released","status":"Completed","viewCount":797,"destinationType":[],"lastUpdated":"01/27/25","favorited":false,"detailedFunding":false,"projectContacts":[],"programContacts":[{"contactId":206378,"canUserEdit":false,"firstName":"Jason","lastName":"Kessler","fullName":"Jason L Kessler","fullNameInverted":"Kessler, Jason L","middleInitial":"L","email":"jason.l.kessler@nasa.gov","receiveEmail":"Subscribed_User","programContactRole":"Program_Director","programContactId":607,"programId":73,"programContactRolePretty":"Program Director","projectContactRolePretty":""},{"contactId":62051,"canUserEdit":false,"firstName":"Carlos","lastName":"Torrez","fullName":"Carlos Torrez","fullNameInverted":"Torrez, Carlos","email":"carlos.torrez@nasa.gov","receiveEmail":"Subscribed_User","programContactRole":"Program_Manager","programContactId":606,"programId":73,"programContactRolePretty":"Program Manager","projectContactRolePretty":""}],"leadOrganization":{"organizationId":4852,"organizationName":"Langley Research Center","acronym":"LaRC","organizationType":"NASA_Center","city":"Hampton","stateTerritoryId":7,"stateTerritory":{"abbreviation":"VA","country":{"abbreviation":"US","countryId":236,"name":"United States"},"countryId":236,"name":"Virginia","stateTerritoryId":7,"isTerritory":false},"country":{"abbreviation":"US","countryId":236,"name":"United States"},"countryId":236,"zipCode":"23681","projectId":5021,"projectOrganizationId":35840,"organizationRole":"Lead_Organization","canUserEdit":false,"locationEdit":false,"organizationRolePretty":"Lead Organization","organizationTypePretty":"NASA Center"},"otherOrganizations":[{"organizationId":4852,"organizationName":"Langley Research Center","acronym":"LaRC","organizationType":"NASA_Center","city":"Hampton","stateTerritoryId":7,"stateTerritory":{"abbreviation":"VA","country":{"abbreviation":"US","countryId":236,"name":"United States"},"countryId":236,"name":"Virginia","stateTerritoryId":7,"isTerritory":false},"country":{"abbreviation":"US","countryId":236,"name":"United States"},"countryId":236,"zipCode":"23681","projectId":5021,"projectOrganizationId":35840,"organizationRole":"Lead_Organization","canUserEdit":false,"locationEdit":false,"organizationRolePretty":"Lead Organization","organizationTypePretty":"NASA Center"},{"organizationId":2660,"organizationName":"CFD Research Corporation","organizationType":"Industry","city":"Huntsville","stateTerritoryId":18,"stateTerritory":{"abbreviation":"AL","country":{"abbreviation":"US","countryId":236,"name":"United States"},"countryId":236,"name":"Alabama","stateTerritoryId":18,"isTerritory":false},"country":{"abbreviation":"US","countryId":236,"name":"United States"},"countryId":236,"zipCode":"35806","dunsNumber":"185169620","uei":"V3KCP1HNFM33","cageCode":"ODEW1","projectId":5021,"projectOrganizationId":33307,"organizationRole":"Supporting_Organization","canUserEdit":false,"locationEdit":false,"organizationRolePretty":"Supporting Organization","organizationTypePretty":"Industry"}],"primaryTx":{"taxonomyNodeId":11445,"taxonomyRootId":8817,"parentNodeId":11441,"code":"TX15.1.4","title":"Aeroacoustics","description":"Aeroacoustics is a branch of acoustics that studies noise generation via either turbulent fluid motion or aerodynamic forces interacting with surfaces, including periodically varying flows, such as shock waves and noise generated by landing gears and deflected aero surfaces, and nonperiodic unsteady flows, such as those encountered during the ascent of launch vehicles and spacecraft.","exampleTechnologies":"The technologies involved include an integrated approach to computational predictive methods, sensors, and test techniques to study aeroacoustic effects generated by shock motion, flow separation and reattachment, exhaust plumes and plume impingement, and sonic booms.
