Cylinder-Infinite-Connect-Four is Connect-Four played on a cylindrical square grid board with infinite row height and columns that cycle about its width. In previous work, the first player’s cannot-lose strategies have been discovered for all widths except 2 and 6, and the second player’s cannot-lose strategies have been discovered with all widths except 6 and 11. In this paper, we show the fir...
flow structure and heat transfer characteristics around two-equal in-tandem square cylinders in the two dimensional laminar and turbulent flow regimes are simulated numerically for reynolds and prandtl numbers, re=1-1×10 5 , pr=0.71, respectively. the investigation is based on an implicit finite volume scheme for integrating the unsteady navier-stokes equations and use of standard κ-ε model to ...
In this paper, the flow-induced oscillation of a prismatic body, viz., a square section cylinder (test cylinder) under interference conditions is analysed considering it as representing a typical building structure. The analysis is carried out using a data-mining tool called ‘Decision Tree’ mainly in view of assessing the safety of the structure (test cylinder) with respect to the vibratory amp...
A narrow strip has been introduced as a control element to suppress vortex shedding from a cylinder. The strip is set parallel to the cylinder axis, and the key parameter of control in this study is the strip position, which is determined by the angle of attack of the strip and the distance between the strip and the cylinder axis. A circular cylinder and a square cylinder were tested respective...
The objective of this study is to develop a method of controlling vortex shedding behind a bluff body using control theory. A suboptimal feedback control procedure for local sensing and local actuation is developed and applied to the flow behind a circular cylinder. The location of sensors for feedback is limited to the cylinder surface and the control input from actuators is the blowing and su...
Abstract This paper investigates the effect of fitting fins at corners a square cylinder on aerodynamic characteristics via wind tunnel tests and large eddy simulations (LES). Although it has been recognized that corner have remarkable cylinder, no study carried out to systematically evaluate this reveal underlying mechanism. Three types fin configurations, i.e. fitted only leading corners, tra...
