Stability of Fully Nonlinear Stokes Waves on Deep Water: Part 1. Perturbation Theory
Shahrdad G. Sajjadi, David L. Ross
We consider a full set of harmonics for the Stokes wave in deep water in the absence of viscosity, and examine the role that higher harmonics play in modifying the classical Benjam…
Growth of unsteady wave groups by shear flows
S. G. Sajjadi, J. C. R. Hunt, F. Drullion
A weakly nonlinear theory has been proposed and developed for calculating the energy- transfer rate to individual waves in a group. It is shown what portion of total energy- transf…
An asymptotic analysis for generation of unsteady surface waves on deep water by turbulence
S. G. Sajjadi
The detailed mathematical study of the recent paper by Sajjadi, Hunt and Drullion (2014) is pre- sented. The mathematical developement considered by them, for unsteady growing mono…
Growth of Stokes Waves Induced by Wind on a Viscous Liquid of Infinite Depth
S. G. Sajjadi
The original investigation of Lamb (1932, §349) for the effect of viscosity on monochromatic surface waves is extended to account for second-order Stokes surface waves on deep wate…
Wave Motion Induced By Turbulent Shear Flows Over Growing Stokes Waves
Shahrdad G. Sajjadi, Sarena Robertson, Rebecca Harvey +1
The recent analytical of multi-layer analyses proposed by Sajjadi, Hunt and Drullion (2014) (SHD14) is solved numerically for atmospheric turbulent shear fows blowing over unsteady…
Formation of three-dimensional surface waves on deep-water using elliptic solutions of nonlinear Schrödinger equation
Shahrdad G. Sajjadi, Stefan C. Mancas, Frederique Drullion
A review of three-dimensional waves on deep-water is presented. Three forms of three dimensionality, namely oblique, forced and spontaneous type, are identified. An alternative for…
Micro cavitation bubbles on the movement of an experimental submarine Theory and Experiments
Stefan C. Mancas, Shahrdad G. Sajjadi, Asalie Anderson +1
To further understand their nature, micro cavitation bubbles were systematically diffused around the exterior of a test body (tube) fully submerged in a water tank. The primary pur…
Asymptotic Multi-Layer Analysis of Wind Over Unsteady Monochromatic Surface Waves
S. G. Sajjadi, J. C. R. Hunt, F. Drullion
Asymptotic multi-layer analyses and computation of solutions for turbulent flows over steady and unsteady monochromatic surface wave are reviewed, in the limits of low turbulent st…
