This paper describes the work done in the development of a fast and accurate numerical solver for flows around flapping wings at low Reynolds numbers. In the rst part, the fi...
The paper presents numerical results of optimized airfoils at ultra-low Reynolds numbers. These investigations are carried out to understand the aerodynamic issues related to the low speed and micro...
Growing interest in micro-air-vehicles has created the need for improved understanding of the relevant aerodynamics. A reasonable starting point is the study of airfoil aerodynamics at Reynolds nu...
Transonic flow over a thin airfoil at low Reynolds number was studied numerically by directly solving two-dimensional full Navier-Stokes equations through 5th order weighted essentially non-oscillator...
Abstract: We analyse the anisotropy of homogeneous turbulence in an electrically conducting fluid submitted to a uniform magnetic field, for low magnetic Reynolds number, in the quasi- static approxim...
Spanwise flexibility is a key factor influencing propulsion performance of pectoral foils. Performances of bionic fish with oscillating pectoral foils can be enhanced by properly selecting the spanwis...
The Xu {&} Yan scale-adaptive simulation (XY-SAS) model is employed to simulate the flows past wavy cylinders at Reynolds number 8\times 10^3 . This approach yields results in good agreement with expe...
Starting from the Navier-Stokes and the continuity equations of a viscous incompressible fluid, a statistical theory is developed for the prediction of transition and break down to turbulence in a lam...
A direct numerical simulation of a turbulent channel ?ow, with regularly spaced two-dimensional roughness elements mounted at the wall and perpendicular to the ?ow direction, was performed at a very l...
An efficacy of some κ-ε turbulence models applying to solve turbulent flow field around a ship model was evaluated. Five κ-ε turbulence models were selected from a viewpoint of low Reynolds number ef...
Flow over an oscillating cylinder at Re = 300 is simulated. For in–line oscillations, the vortex–shedding frequency locks–on the cylinder frequency in a wide frequency band, around twice the natural v...
