Analysis of Flow Past a Cylinder Attached to a Spring
The flow of fluid past a cylinder has been widely studied both analytically and numerically, and provides insight to the behavior of flow given different fluid properties. Particularly interesting is the transition from steady flow to vortex shedding in the wake of the cylinder. This behavior is dependent on several parameters, but most importantly, the Reynolds number (Re), which is a dimensio...
متن کاملNumerical Simulation of the Incompressible Laminar Flow Over a Square Cylinder
Simulation of fluid flow over a square cylinder can be performed in order to understand the physics of the flow over bluff bodies. In the current study, incompressible laminar flow over a confined square cylinder, with variable blockage factor has been simulated numerically, using computational fluid dynamics (CFD). The focus has been on vortex-induced vibration (VIV) of the cylinder. Vorticity...
متن کاملNumerical Simulation of Fluid Flow Past a Square Cylinder Using a Lattice Boltzmann Method
The method of lattice boltzmann equation(LBE) is a kinetic-based approach for fluid flow computations. In the last decade, minimal kinetic models, and primarily the LBE, have met with significant success in the simulation of complex hydrodynamic phenomena, ranging from slow flows in grossly irregular geometries to fully developed turbulence, to flow with dynamic phase transitions. In the presen...
متن کاملA Shock Wave Attached to a Pointed Obstacle in a Steady Flow of a Dissociating Gas
A pointed obstacle is assumed symmetrically placed with respect to a uniform supersonic flow ahead of it. It ia as~umed that an oblique shock wave attached to the leading edge of the obstacle appears from the vertex so that the flow after the shock is along the surface of the obstacle. In this paper a relation between the curvature of an attached shock wave and that of a stream line is discover...
متن کاملNon-similar Solution of a Steady Compressible Boundary Layer Flow over a Thin Cylinder
The aim of this paper is to present non-similar solutions of a steady laminar compressible boundary layer flow past a long thin circular cylinder including the effects of wall enthalpy and surface mass transfer. The governing equations along with the boundary conditions are first converted into dimensionless form by a non-similar transformation, and then the resulting system of coupled non-line...
