Numerical study of rigid and flexible wing shapes in hover

Aerodynamic Hovering Performance of Rigid and Flexible Wing Planform Shapes

Wing geometric parameters govern the aerodynamic performance of insects and micro aerial vehicles. Previous studies of wing shapes have been limited to rigid wings. The aerodynamic hovering performance of rigid and flexible wing shapes for aspect ratio AR = 1.5 is evaluated computationally at the Reynolds number (Re) of 400. The three-dimensional viscous incompressible Navier-Stokes equations a...

A numerical study of vortex dynamics of flexible wing propulsors

The dynamic properties such as time dependent pressure loading, speed, free stream velocity, and local acceleration of the hydrofoil determine the instantaneous deformation of the hydrofoil, which has effect on the propulsive characteristics of the aquatic animal. A potential flow analysis is done on the flexible hydrofoil, to evaluate the both inertial and elastic effects on propulsive charact...

Numerical Geometry of Non-Rigid Shapes

a contrastive study of rhetorical functions of citation in iranian and international elt scopus journals

writing an academic article requires the researchers to provide support for their works by learning how to cite the works of others. various studies regarding the analysis of citation in m.a theses have been done, while little work has been done on comparison of citations among elt scopus journal articles, and so the dearth of research in this area demands for further investigation into citatio...

study of wing shapes influence on mav aerodynamic coefficients

in recent years, design of small aircrafts are studied and extensively developed. one of the most important of these aircrafts is micro aerial vehicles (mavs). as part of aerodynamic design of mavs, the wing design is important. in fact, the main part of this design is to find an appropriate shape for the wing. in this work, influence of the wing shape at low reynolds number flow is investigate...
