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 …
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 …
Modeling of Wind Flow Around Obstructions to Aid Wind Turbine Placement Decisions
Renewable energy such as solar and wind power is becoming increasingly important in reducing effects of global warming. The One Energy wind power company installs wind turbines on local properties instead of dedicated wind farms, in which case there are no industry standards how small single obstructions, such as from …
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 …
Simulation of Heating to Promote Drug Mixing in the Eye
The leading cause of central vision loss in the developed world is from age-related macular degeneration (AMD). Although certain types of AMD can generally be managed with injections of anti-VEGF agents, the treatment is sometimes ineffective. The linked study examines how this type of treatment potentially can be …
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 …
Flow Around a Cylinder
Benchmark problem for stationary, laminar, and incompressible flow around a cylinder. Although it is not possible to derive an analytical solution to this test case, very accurate numerical solutions to benchmark reference quantities have been established for the pressure difference, drag, and lift coefficient [1],[2]. …
