UNSTABLE ROTATIONAL FLOW AROUND AN AIR TUBE

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...

Kinetic Simulation of Air Flow Around Hollow Cylinder Flare Configuration

Kinetic approach was used to study the shock wave/boundary layer interaction in diatomic gases and gas mixtures. The effect of non-equilibrium processes on the steady state solution was studied.

Laminar and Turbulent Aeroheating Predictions around Multi -Cone Configurations in Hypersonic Equilibrium - Air Flow

Experimental Results of Pressure Fluctuations in a Water Conduit Section Due to Formation of Unstable Two-Phase Air-Water Flow

The study of two-phase fluid flow behavior in hydraulic structures such as pressurized flow tunnels, culverts, sewer pipes, junctions and other similar conduits is of great importance. A two-phase mixture flowing in a pipe can exhibit several interfacial geometries such as bubbles, slugs or films, depending on the fluid and hydrodynamic properties of flow. The main variables, giving rise to a v...

Numerical Simulation of Air-He Shock Tube Flow with Equilibrium Air Model

In this study, a compressible multi-component Navier-Stokes flow solver with real gas effect is developed for studying the high-speed flow in an air-He shock tube. For compressible multi-component flow simulation, a reduced five-equation model in conjunction with HLLC approximate Riemann solver is employed. For the real gas effect, a curve-fitting approximation for equilibrium air constructed f...
