The study is motivated by the gliding flight of dragonflies and its relevance to bio-inspired corrugated wing design for Micro Air Vehicles. The detailed flow field measurements are undertaken at 6% free stream turbulence intensity for six angles of attack (±50, ±100 and ±150). The low Reynolds number regime from Re= 1200 to 13200 corresponding to dragonfly flight has been covered in the current study. The aerodynamic performance of the corrugated airfoil is evaluated by obtaining drag and lift coefficients using modified wake survey method and Kutta-Joukowski theorem respectively. The calculated Cl and Cd are compared with available literature and it is noted that the performance of corrugated profile airfoil degrades significantly under the influence of external turbulence. The temporal wake obtained from the mean velocity fields is also presented for better visualization of flow dynamics. The findings of the study indicate that the performance of corrugated airfoil under external turbulence is strongly influenced by angle of attack at lower Re.","PeriodicalId":41984,"journal":{"name":"JOURNAL OF FLOW VISUALIZATION AND IMAGE PROCESSING","volume":"83 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"136002871","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}

A quantitative research design is adopted to assess verbal/visual performance using eye-tracking technology. The study recruited sixty-two students. The responses of participants were collected regarding the verbal-visual learning style rating (VVLSR). This study used eyetracking technology and assessed the verbal/visual performance of the participants. Fixation count on the map (FCm), Fixation count on the text (FCt), fixation duration on the map (FDm), and fixation duration on the text (FDt) were involved in the measures. Statistical analysis was performed through one-way analysis of variance (ANOVA) and Pearson correlation. Data were gathered with the Tobii X120 and collected with Tobii Studio. The findings revealed a significant relationship between text duration and verbal score (r = 0.543, p < 0.001). One-way ANOVA findings showed a significant impact of learning style on the visual test [F (2.59) = 6.26, p = 0.003]. No significa nt effect of learning style was reported on the verbal test [F (2.59) = 0.957, p = 0.390)]. The study has provided evidence of the effectiveness of visuals in multimedia learning environments. The participants' perceptions varied about the learning procedure. The study found a significant positive impact of using visual and verbal information for better learning and knowledge retention. In the future, the VVLSR will add value to the research in applied cognitive psychology as it will help the psychologist to identify the effects of different verbal/visual learning styles via eye-tracking technology.","PeriodicalId":41984,"journal":{"name":"JOURNAL OF FLOW VISUALIZATION AND IMAGE PROCESSING","volume":"1 1","pages":""},"PeriodicalIF":0.6,"publicationDate":"2023-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"67593880","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}
