“…They observed a complete suppression of vortex shedding phenomena at a relatively high rotation rate. [5] and [21] showed the existence of multiple lock-in regions in the flow past a circular cylinder subjected to a circular motion. [20] showed that the flow topology can be significantly affected by sinusoidal rotations of a cylinder placed in a flow.…”

The drag reduction on a circular cylinder through rotational oscillations is globally maximized by coupling a CFD solver with a novel parallel global deterministic optimization algorithm. The simulations are performed at a Reynolds number of 150 and the amplitude and frequency of the rotational oscillations are respectively constrained to the ranges 0.1 ≤ Ω ≤ 1.0 and 0.1 ≤ f Ω ≤ 3.0. The novelty of this work lies in the use of a massively parallel derivative free optimization algorithm to find the globally (not locally, as is typically done) optimal values of

“…Therefore, many numerical techniques have been developed to solve such type of problems. These methods include Adomian's decomposition method, homotopy perturbation method, variational iteration method, optimal homotopy asymptotic method, operational matrices techniques based on various orthogonal polynomials and wavelets, finite difference method, and spectral methods; the reader is referred to [1][2][3][4][5][6] and references therein.…”

We present an efficient iterative power series method for nonlinear boundary-value problems that treats the typical divergence problem and increases arbitrarily the radius of convergence. This method is based on expanding the solution around an iterative initial point. We employ this method to study the unsteady, viscous, and incompressible laminar flow and heat transfer over a shrinking permeable cylinder. More precisely, we solve the unsteady nonlinear Navier-Stokes and energy equations after reducing them to a system of nonlinear boundary-value problems of ordinary differential equations. The present method successfully captures dual solutions for both the flow and heat transfer fields and a unique solution at a specific critical unsteadiness parameter. Comparisons with previous numerical methods and an exact solution verify the validity, accuracy, and efficiency of the present method.
