Supersonic Turbulent Flow Past a Prism
Supersonic Turbulent Flow Past a Prism
This tutorial example sets up and solves supersonic compressible flow around a triangular prism, with viscous effects and turbulence using the OpenFOAM solver. The inflow is supersonic at 650 m/s causing shock waves to form when the flow field impacts the prism, and also secondary waves following the trailing edges and …
Supersonic Flow Past a Wedge
Supersonic Flow Past a Wedge
This verification test case studies steady inviscid compressible flow past a wedge at an incident angle of 15 degrees. As the supersonic flow (Ma = 2.5) hits the wedge a sharp oblique shock wave is formed, resulting in a reduced downstream flow velocity. The simulation uses the inviscid compressible Euler equations to …
Surface Currents in a Circular Wire
Surface Currents in a Circular Wire
Skin effect is a phenomenon where an alternating current tends to flow and distribute itself along the surface layer or outside skin of a conductor. This effect can for example be taken advantage of in power transmission applications by layering inexpensive conductor materials (for example aluminium) with a thin layer …
Multi-body System Simulation for Design of Optical Grating Tiling Devices
Multi-body System Simulation for Design of Optical Grating Tiling Devices
The research presented in the paper “Development of Dynamics for Design Procedure of Novel Grating Tiling Device with Experimental Validation” uses FEATool Multiphysics in a novel dynamics for design (DFD) multi body system (MBS) loop to develop new grating tiling devices, such as used in spectroscopy and …
Non-Newtonian Flow in an Extrusion Die
Non-Newtonian Flow in an Extrusion Die
This example models flow of a polymer through an extrusion die with two outlets. This type of flow can for example be found in manufacturing processes of plastic parts. The polymer is assumed to be non-Newtonian, and can be modeled with a shear thinning Bird-Carreau viscosity model. The die is also assumed to be …
Temperature Loading of a Tapered Cylinder
Temperature Loading of a Tapered Cylinder
This validation test case models temperature loading of a tapered hollow thick cylinder with a spherical bottom flange section. The solid object is assumed to be clamped vertically, but allowed to expand horizontally due to a linear temperature gradient. The stress in the z-direction at the bottom inner point is …
Electro-Osmotic Flow
Electro-Osmotic Flow
This multiphysics example examines microfluidic flow and coupled mass transport due to electroosmosis in a channel with a T-shaped junction. With application of an electric field in a micro channel a flow effect is induced along the walls due to chemical reactions between the liquid and the wall material. This effect …
