The Lattice-Boltzmann method is currently being explored as an alternative flow solver for use in high-speed or real-time applications like pilot flight simulators. Because of its localized solution, the highly parallelizable nature of the Lattice-Boltzmann method make it an idea candidate for GPU computing. The Lattice-Boltzmann framework used in this study is a GPU accelerated version of the OpenLB C++ library. The traditional LBM models fluid domain as a set of square lattices aligned to a Cartesian grid. While this allows for a much more computationally efficient analysis, this can result in challenges when modeling solid structures within the fluid flow, as the objects are often represented with a staircase approximation. Different boundary conditions that account for curved geometry are implemented in the current Lattice-Boltzmann framework and different near-body flow parameters are evaluated for complex geometric shapes. The boundary condition treatments were implemented using both no-slip\/non-moving wall assumptions and moving-wall\/slip assumptions. The effects of resolution and domain size on the near body solution were also analyzed. The effects that the applied boundary conditions had on the far-field flow were analyzed to determine if the near-body flow results had a significant impact on the flow downstream. It was found that different types of boundary treatments had little effect on the near-body flow solution, but the slip vs. no-slip assumption had a significant impact on the near-body results. Namely, by applying a boundary treatment with a slip assumption, the limited flow separation expected around a body was captured, whereas the no-slip boundary treatment typically caused the flow separation field around the object to be overestimated. The no-slip boundary conditions, in addition to giving a less accurate near-body flow solution, also had greater fluctuations and more energy in the far-field, indicating that the no-slip boundary condition may create more wake effects in addition to providing a less accurate near-body solution.\u0026nbsp;\u003C\/p\u003E\r\n\r\n\u003Cp\u003E\u003Cstrong\u003ECommittee\u003C\/strong\u003E\u003C\/p\u003E\r\n\r\n\u003Cul\u003E\r\n\t\u003Cli\u003EProf. Juergen Rauleder \u0026ndash; School of Aerospace Engineering (advisor)\u003C\/li\u003E\r\n\t\u003Cli\u003EProf. Marilyn Smith \u0026ndash; School of Aerospace Engineering\u003C\/li\u003E\r\n\t\u003Cli\u003EProf. Lakshmi Sankar \u0026ndash; School of Aerospace Engineering\u003C\/li\u003E\r\n\u003C\/ul\u003E\r\n\r\n\u003Cp\u003E\u0026nbsp;\u003C\/p\u003E\r\n","summary":null,"format":"limited_html"}],"field_subtitle":"","field_summary":"","field_summary_sentence":[{"value":"Evaluation of Boundary Condition Treatments and Environments for Improved Near-Body Solutions in Lattice-Boltzmann Flow Simulations "}],"uid":"27707","created_gmt":"2022-04-26 15:21:19","changed_gmt":"2022-04-26 15:21:19","author":"Tatianna Richardson","boilerplate_text":"","field_publication":"","field_article_url":"","field_event_time":{"event_time_start":"2022-05-04T10:00:00-04:00","event_time_end":"2022-05-05T00:00:00-04:00","event_time_end_last":"2022-05-05T00:00:00-04:00","gmt_time_start":"2022-05-04 14:00:00","gmt_time_end":"2022-05-05 04:00:00","gmt_time_end_last":"2022-05-05 04:00:00","rrule":null,"timezone":"America\/New_York"},"extras":[],"groups":[{"id":"221981","name":"Graduate Studies"}],"categories":[],"keywords":[{"id":"111531","name":"ms defense"}],"core_research_areas":[],"news_room_topics":[],"event_categories":[{"id":"1788","name":"Other\/Miscellaneous"}],"invited_audience":[{"id":"78761","name":"Faculty\/Staff"},{"id":"78771","name":"Public"},{"id":"78751","name":"Undergraduate students"}],"affiliations":[],"classification":[],"areas_of_expertise":[],"news_and_recent_appearances":[],"phone":[],"contact":[],"email":[],"slides":[],"orientation":[],"userdata":""}}}
