The research is aimed at suppressing unsteady loads resulting from the von-Kármán vortex shedding in the wake of bluff-bodies at a Reynolds number range of 100–1,000. A low-dimensional proper orthogonal decomposition (POD) procedure was applied to the stream-wise and cross-stream velocities in the near wake flow field, with steady-state vortex shedding, obtained using particle image velocimetry (PIV). Data were collected in the unforced condition, which served as a baseline, as well as during influence of forcing within the “lock-in” region. The design of sensor number and placement was based on data from a laminar direct numerical simulation of the Navier-Stokes equations. A linear stochastic estimator (LSE) was employed to map the surface-mounted hot-film sensor signals to the temporal coefficients of the reduced order model of the wake flow field in order to provide accurate yet compact estimates of the low-dimensional states. For a three-sensor configuration, results show that the estimation error of the first two cross-stream modes is within 20–40% of the PIV-generated POD time coefficients. Based on previous investigations, this level of error is acceptable for a moderately robust controller required for feedback flow control."],"license_tesim":["http://rightsstatements.org/vocab/InC/1.0/"],"date_created_tesim":["2007-02"],"source_tesim":["Experiments in Fluids"],"thumbnail_path_ss":"/downloads/bc386t63s?file=thumbnail","suppressed_bsi":false,"actionable_workflow_roles_ssim":["admin_set/default-default-depositing"],"workflow_state_name_ssim":["deposited"],"member_ids_ssim":["bc386t63s"],"file_set_ids_ssim":["bc386t63s"],"visibility_ssi":"open","admin_set_tesim":["Default Admin Set"],"sort_title_ssi":"EXPERIMENTAL ESTIMATION OF A DSHAPED CYLINDER WAKE USING BODYMOUNTED SENSORS","human_readable_type_tesim":["Article"],"read_access_group_ssim":["public"],"read_access_person_ssim":["konecnmc@ucmail.uc.edu"],"edit_access_person_ssim":["cohenky@ucmail.uc.edu"],"nesting_collection__pathnames_ssim":["bc386t62h"],"nesting_collection__deepest_nested_depth_isi":1,"_version_":1697123931626930176,"timestamp":"2021-04-15T16:18:25.351Z","score":0.00049999997}],"facets":[{"name":"human_readable_type_sim","items":[{"value":"Article","hits":1,"label":"Article"}],"label":"Human Readable Type Sim"},{"name":"creator_sim","items":[{"value":"Cohen, Kelly","hits":1,"label":"Cohen, Kelly"},{"value":"Fono, Ilan","hits":1,"label":"Fono, Ilan"},{"value":"Palei, Vitali","hits":1,"label":"Palei, Vitali"},{"value":"Seifert, Avi","hits":1,"label":"Seifert, Avi"},{"value":"Stalnov, Oksana","hits":1,"label":"Stalnov, Oksana"}],"label":"Creator Sim"},{"name":"subject_sim","items":[],"label":"Subject Sim"},{"name":"college_sim","items":[{"value":"Engineering and Applied Science","hits":1,"label":"Engineering and Applied Science"}],"label":"College Sim"},{"name":"department_sim","items":[{"value":"Aerospace Engineering and Engineering Mechanics","hits":1,"label":"Aerospace Engineering and Engineering Mechanics"}],"label":"Department Sim"},{"name":"language_sim","items":[{"value":"English","hits":1,"label":"English"}],"label":"Language Sim"},{"name":"publisher_sim","items":[],"label":"Publisher Sim"},{"name":"date_created_sim","items":[{"value":"2007-02","hits":1,"label":"2007-02"}],"label":"Date Created Sim"},{"name":"member_of_collection_ids_ssim","items":[],"label":"Member Of Collection Ids Ssim"},{"name":"generic_type_sim","items":[{"value":"Work","hits":1,"label":"Work"}],"label":"Generic Type Sim"}],"pages":{"current_page":1,"next_page":null,"prev_page":null,"total_pages":1,"limit_value":10,"offset_value":0,"total_count":1,"first_page?":true,"last_page?":true}}}
