AI and Deep Learning CFD Model for Flow Prediction
In a series of publications Prof. Thi-Thu-Huong Le, Hoyeun Kang, and colleagues from Pusan National University (PNU) in Korea, have successfully developed a new deep learning (DL) CFD methodology for flow prediction using FEATool Multiphysics with AI and machine learning. Although traditional Computational Fluid …
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
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 …
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 …
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 …
Multi-Simulation Heat Exchanger
This tutorial model illustrates how one can couple the OpenFOAM CFD solver with the FEATool Multiphysics FEA solver. In the model a stream of cool air is heated while flowing through a tube and fin heat exchanger. Due to several symmetry planes only a small section of the full heat exchanger geometry actually needs to …
Turbulent Channel Flow
Simulation of stationary and incompressible turbulent flow between two parallel flat plates at Reynolds number 42800. A fully developed turbulent velocity profile is formed at the outflow boundary which can be compared to experimental results (Laufer, J. 1950). This example uses both the built-in algebraic mixing …
Turbulent Flow Over a Backwards Facing Step (OpenFOAM)
Flow over backwards facing steps are classic computational fluid dynamics test problems, and are often used for validation of simulation codes. This test problem consists of studying how the flow field reacts to a sudden expansion in a channel. The expansion will cause a break in the flow and a recirculation or …
Natural Convection in a Square Cavity
This multiphysics model illustrates natural convection effects in a unit square domain using the Boussinesq approximation. The model involves a Navier-Stokes equations physics mode, representing the fluid flow with solid wall or no-slip boundary conditions everywhere. In addition a heat transfer physics mode is added …
Axisymmetric Fluid Flow
FEATool is designed to be able to perform complex multiphysics simulations in arbitrary dimensions (1D, 2D, and 3D). However, running full 3D simulations often requires a significant amount of computational resources in the form of memory and simulation time. It is therefore desirable to find simplifications to reduce …
