Stability problem of an axisymmetric swirling flow a viscous incompressible fluid with respect to nonaxisymmetric perturbations is considered. The system ordinary differential equations for the amplitude functions solved numerically by Runge-Kutta method and orthogonalization procedure. Solutions at neighborhood singular points are obtained Frobenius method. maximum amplification coefficients phase velocities five unstable modes calculated.

Numerical Investigation of Vortex Interaction in Pipe Flow
To discover the nonlinear characteristics of pipe flow, we simulated the flow as a sum of many vortex rings. As a first step, we investigated the nonlinear interaction among a maximum of three vortex rings. The pipe wall was replaced by many bound vortices. A free vortex ring moves right or left according to the radius, and that of a particular radius keeps the initial position. The energy of a...

چکیده: فرض کنید که تابعی از اپسیلون یک مجموع نامتناهی از احتمالات موزون مربوط به مجموع های جزئی براساس یک دنباله از متغیرهای تصادفی مستقل و همتوزیع باشد، و همچنین فرض کنید توابعی مانند g و h وجود دارند که هرگاه امید ریاضی توان دوم x متناهی و امیدریاضی x صفر باشد، در این صورت می توان حد حاصلضرب این توابع را بصورت تابعی از امید ریاضی توان دوم x نوشت. حالت عکس نیز برقرار است. همچنین ما با استفاده...
15 صفحه اولAsymptotic and Numerical Techniques for Resonances of Thin Photonic Structures
We consider the problem of calculating resonance frequencies and radiative losses of an optical resonator. The optical resonator is in the form of a thin membrane with variable dielectric properties. This work provides two very different approaches for doing such calculations. The first is an asymptotic method which exploits the small thickness and high index of the membrane. We derive a limiti...
متن کاملStability of Vortex Pairs over Slender Conical Bodies: Analysis and Numerical Computation
A N INITIALLY symmetric vortex pair over a slender pointed body or wing–body combination, such as that shown in Fig. 1, becomes asymmetric as the angle of attack is increased beyond a certain value, causing large rolling moments in the case of swept wings or large side forces in the case of slender bodies, even at zero roll and yawing angles. At even larger angles of attack, unsteady vortex she...
متن کاملNumerical Simulation of the Wake Flow Behind an Ellipse using Random Vortex Method (RESEARCH NOTE)
Direct numerical simulation of the wake flow around and behind a planar ellipse using a random vortex method is presented. Fluid is considered incompressible and the aspect ratios of ellipse and the angles of attacks are varied. This geometry can be a logical prelude to the more complex geometries, but less time dependent experimental measurements are available to validate the numerical results...
