What you'll learn

  • Analysis of Flow Through Multiple Outlets Pipe for Optimized Irrigation System
  • Conjugate Heat Transfer Analysis of a Motherboard in Enclosed Cabinet for Thermal Management
  • Geometry Preparation Using Salome
  • Meshing Using Salome
  • Setting Correct Boundary Conditions in OpenFOAM
  • Post-processing Using Paraview

Course content

2 sections • 16 lectures • 1h 41m total length

  • Introduction and Geometry Preparation in Salome3:17

    Find case files attached to resources.

  • Creating 3D Mesh in Salome with Inflation Layers5:37

    Mesh a cad model in Salome by creating a 2d mesh with Netgen 1d 2d, convert to 3d with 5 mm boundary layers, and export an unv file for OpenFOAM.

  • Importing the Mesh in OpenFOAM4:35

    Import and prepare a Salome-generated mesh in OpenFOAM, using Ubuntu, and visualize it in ParaView to verify boundary names and mesh integrity for an incompressible pipe simulation.

  • Setting up Correct Boundary Conditions4:54

    Edit the constant/polymesh/boundary file to set inlet and outlet as patch, walls as wall. Copy to zero and set inlet velocity, no-slip walls, and zero-gradient pressure with outlet zero pressure.

  • k-Epsilon Calculation4:13

    Calculate Reynolds number to identify turbulence, then apply the k-epsilon turbulence model in OpenFOAM, computing k and epsilon and setting fixed value boundary conditions at the inlet and walls.

  • Launching the Simulation using simpleFoam4:17
  • Post-processing of Results in Paraview5:56

Requirements

  • Enthusiasm to learn OpenFOAM

Description

Note - CFD results always need to be validated with experimental data before blindly relying on them.


This course will take you through all the basics required in order to simulate simple CFD problems using OpenFOAM.

  • Geometry preparation will be covered using Salome.

  • Meshing will be covered using Salome.

  • Solving will be covered using OpenFOAM solvers.

  • Post-processing of results will be covered using Paraview.

  • All these software are available for free without any license costs.

CFD helps to reduce the cost of products by saving time and money in prototype testing phase. Rapid prototype testings can be done by using CFD technology to predict the future behavior of the product. It enables us to foresee any shortcomings in the product and rectify them before the actual manufacturing phase of the product. This is a young technology and can grow substantially in near future.


You will be able to draw CAD models using the dimensions of any given geometry. Then you will understand how to import CAD model in Salome and mesh the geometry in Salome to get appropriate results. Mesh size plays an important role in deciding the accuracy of your results. Assumption of boundary conditions is another important aspect in any CFD simulation. Replication of real-life conditions must be correctly implemented in the CFD boundary conditions. Finally good post-processing of the results helps you to deliver your results successfully to the non-technical.
