The fluid-structure interaction of an elastically restrained inclined tangent ogive-cylindrical body with a blunt elliptical base is investigated numerically. The flow is three-dimensional, compressible, and laminar, and the slender body is allowed t

In this research, we employ a computational methodology to investigate the self-excited angular dynamics of an elastically restrained rigid body in uniform compressible laminar flow. We investigate the onset of vortex-induced vibration of a two-dimen

Separation control by two-dimensional periodic excitation is studied theoretically for nonsymmetrical flows over a parabola using a mathematical model of incompressible laminar flow with periodic perturbations. This model is based on the representati

The problem of coherent perturbations in a turbulent shear layer is considered for the purpose of developing a mathematical model based on a triple decomposition that extracts the coherent components of random fluctuations. The governing equations fo

The problem of expansion of a dilute granular gas consisting of smooth, inelastic hard spheres into vacuum was investigated by three different methods: both (1) analytical and (2) computational (CFD) treatments of a hydrodynamic model, and (3) by Dis

The current work investigates numerically rolling instabilities of a free-to-roll slender rigid-body of revolution placed in a wind tunnel at a high angle of attack. The resistance to the roll moment is represented by a linear torsion spring and equi

Tropospheric wave propagation can be described by a parabolic differential equation which may be solved using implicit finite differences. The large grid systems which can be required in such solutions make parallelization expedient. This can be acco

Recently, large efforts were directed to numerical simulations of high-incidence flows around slender bodies of revolution to gain more insight into the problem of flow asymmetry. One of the significant advantages in using numerical simulation to inv
