As computer hardware has evolved, the time required to perform numerical simulations has
reduced, allowing investigations of a wide range of new problems. This thesis focuses on …

Phase screens are widely used to simulate the effects of atmospheric turbulence on the
phase fluctuations of a light beam. We compare three sampled-based phase-screen …

In this paper, we have studied the effect of residual aliasing error of the second order Runge–
Kutta (RK2) based Random Phase Shift Method (RPSM) which shows smoothing effect in …

In addition to conserving energy and enstrophy, the nonlinear terms of the two-dimensional
incompressible Navier–Stokes equation are well known to conserve the global integral of …

Resonance phenomena are ubiquitous in Nature. Resonance means that a system can
accumulate large amounts of kinetic energy. In rotating flows inertial waves provide a …

Turbulence is a ubiquitous phenomenon that occurs throughout the universe, in both neutral
fluids and plasmas. For collisionless plasmas, kinetic effects, which alter the nonlinear …
