My research interest focuses on modeling and analysis of multi-disciplinary complex physical systems where strongly coupled interaction plays an important role. For my undergraduate research on the aerodynamics of a high-altitude kite, I studied the interaction between the aerodynamics, structural dynamics, and control of the kite and the cable configuration in a team of eight students. My mast...

The aerodynamics characteristics of a blended-wing body (BWB) aircraft were obtained in Universiti Teknologi MARA low speed wind tunnel. The scaled-down of BWB model consisted of a canard as its horizontal stabilizer. There were four canards with different aspect ratio used in the experiments. Canard setting angles were varied from -20 to 20 . All tests were conducted at velocity of 35 m/s, wit...

We present a case study in using scientific visualization techniques to qualitatively explore predicted flow fields generated by bats in flight, which resulted in a better insight into methods for studying aerodynamic behavior of bats. Our study involved a qualitative comparison of flow features derived from both Navier-Stokes computations and potential flow computational aerodynamics models. A...

The objective of this study was to document functional results and to compare objective and subjective voice measures after endoscopic laryngoplasty with injection of polydimethylsiloxane (PDMS) for the treatment of unilateral vocal fold paralysis, and to verify PDMS biocompatibility in vocal fold. The design used was a longitudinal prospective study. Fifteen patients with unilateral vocal fold...

Underexpanded jets have become widely used in studies of rarefied-gas flows [1][3] and aerodynamics of hypersonic probes in wind tunnels [4]-[7]. The objective of the present study is to analyze shapes and flow parameters in internal regions of hypersonic underexpanded viscous jets, and to apply the jet theory to hypersonic studies. Analytical solutions [7] are used for estimating internal flow...
