Flow Visualization Around a Non - Circular Tube
The flow behavior around a cam shaped tube in cross flow has been investigated experimentally using flow visualization and pressure distribution measurement. The range of attack angle and Reynolds number based on an equivalent circular diameter are within 0 ≤ α ≤ 360˚ and 2 x 104 < Reeq < 3.4 x 104, respectively. The pressure drag features are clarified in relation to the flow behavior around t...
متن کاملNumerical Study on Hydrodynamic Performance of Bionic Caudal Fin
In this work, numerical simulations are conducted to reveal the hydrodynamic mechanism of caudal fin propulsion. In the modeling of a bionic caudal fin, a universal kinematics model with three degrees of freedom is adopted and the flexible deformation in the spanwise direction is considered. Navier-Stokes equations are used to solve the unsteady fluid flow and dynamic mesh method is applied to ...
متن کاملNumerical Simulation of Flow Past Oscillating Airfoil Using Oscillation of Flow Boundary Condition
The present study is devoted to an approximate modeling for numerical simulation of flows past oscillating airfoils. In this study, it is shown that the harmonic oscillating objects can be studied by simple numerical codes that are not able to solve moving grids. Instead of using moving grid for the simulation of flowfield around an oscillating airfoil, this unsteady flow is solved on a fixed g...
متن کاملA Numerical Study of Flow Around an Oscillating Airfoil with High-Order Spectral Difference Method
A high-order spectral difference flow solver for compressible three-dimensional NavierStokes (N-S) equations has been utilized to numerically simulate the unsteady flow over the NACA 0012 airfoil undergoing a sinusoidal pitching motion at the Reynolds (Re) number of 12600. The effects of the reduced frequency and Strouhal number on the wake vortex structure and force coefficient have been studi...
متن کاملFlow Structure Analysis around an Oscillating Circular Cylinder at Low Kc Number: a Numerical Study
Flow fields around an oscillating circular cylinder are studied by solving the incompressible Navier-Stokes equations in primitive variable formulation. A finite volume method with a pressure predictor-corrector scheme is used and the solution procedure is accelerated by a local time stepping technique. Numerical tests are carried out at the Keulegan-Carpenter number KC < 20 and Reynolds number...
