Passive jet control of flow around a circular cylinder
and suppressing fluctuating amplitude of the dynamic wind loads acting on the test model. With 24 suction/jet holes evenly distributed over the cylindrical test model (i.e., the N13 design of the present study), the passive jet control method was found to be able to achieve up to 33.7 % in drag reduction and 90.6 % in fluctuating wind loading suppression, in comparison with the baseline case. T...
متن کاملSuppression of Vortex Shedding from a Circular Cylinder by using a Traveling Wave Wall
An experimental study was conducted to suppress the unsteady vortex shedding from a circular cylinder by using a traveling wave wall (TWW). The leeward surfaces of the circular cylinder model were replaced by wave surfaces, which can move to form symmetrical TWW when driven by a motor system. The propagation speed of the wave was adjustable by controlling the rotational speed of the motor. Duri...
متن کاملEffect of Wall Conduction on Natural Convection over a Vertical Slender Hollow Circular Cylinder
Abs t rac t . An analysis is made of the laminar natural convection of incompressible fluids over a slender, hollow circular cylinder with the inner surface at a constant temperature of Tb. The temperature of the outer surface must be solved from the coupled conduction of the cylinder and the natural convection of the fluid over the cylinder. The objective of this paper is to investigate the ef...
متن کاملDiffraction theory of an anisotropic circular cylinder.
A fully analytical theory is developed to derive the field diffracted by an infinitely long circular cylinder made of an arbitrary anisotropic homogeneous material, illuminated by an arbitrary plane wave.
متن کاملFlow along a long thin cylinder
Two different approaches have been used to calculate turbulent flow along a long thin cylinder where the flow is aligned with the cylinder. A boundary-layer code is used to predict the mean flow for very long cylinders (length to radius ratio of up to O(10)), with the effects of the turbulence estimated through a turbulence model. Detailed comparison with experimental results shows that the mea...
