How to use Inflation Layers for Boundary Layer Mesh

How to use Inflation Layers for Boundary Layer Mesh

Inflation layers are a commonly used technique to capture the boundary layer accurately in CFD simulations. Here are some general tips for setting inflation layers: ( full table of symbols can be found at the bottom of the page) Calculate the First Layer Height: The first layer height is an important

What is a Mesh?

What is a Mesh?

Why do we need a mesh for CFD? The purpose of the mesh is to represent the geometry of the physical domain in question, the mesh divides the domain into smaller, discrete cells where the governing equations are discretised in order to approximate the fluid flow behaviour at each discrete

How to Make a Good Mesh

How to Make a Good Mesh

Making a good mesh is an important aspect of CFD analysis as the quality of the mesh affects the accuracy and reliability of the simulation results. Here are some general tips for making a good mesh: 1. Consider the geometry of the problem: The mesh should accurately represent the geometry

How to Perform a CFD Simulation

How to Perform a CFD Simulation

To perform cfd simulation, the following steps are typically required: 1. Define the problem: Clearly define the physical problem to be solved, including the geometry of the domain, the fluid flow conditions, and any boundary conditions that need to be applied. 2. Create a mesh: The domain of interest is

Introduction to Computational Fluid Dynamics

Introduction to Computational Fluid Dynamics

What is Computational Fluid Dynamics? Computational Fluid Dynamics (CFD) is a numerical simulation technique used to analyse and predict the behaviour of fluid flows. The method involves solving complex mathematical equations that describe the physical phenomena of fluid flow, heat transfer, and chemical reactions CFD can be used to simulate

High Lift Prediction Workshop

High Lift Prediction Workshop

What is the High Lift Prediction Workshop? The NASA High Lift Prediction Workshop (HLPW) is a collaborative event that brings together researchers and engineers from industry, government and academia to address the challenges of accurately predicting the aerodynamic performance of high-lift devices on aircraft. High-lift systems are essential for safe

Support Systems for Subsonic Wind Tunnel

Support Systems for Subsonic Wind Tunnel

The aim of this project was to design support system mechanisms for the refurbishment of the University of the West of Englands subsonic wind tunnel. The systems designed are: * Sting Support * Side Wall Support * 2D Support * Traverse system * Diffuser nozzle Sting Support System A sting is a fixture where the

HLPW-4: What is Code Verification?

HLPW-4: What is Code Verification?

Code Verification The verification of code is concerned with whether the code is solving equations correctly and does not consider whether the model has any relationship to the real world. Verification evaluates whether the CFD model (the mathematical and computer code representation of the physical system) is solved correctly. This

HLPW-4: Case 3 Turbulence Model Verification

HLPW-4: Case 3 Turbulence Model Verification

The purpose of the study is to demonstrate the accurate and consistent implementation of the standard Spalart-Allmaras turbulence model combined with RANS. This means that different flow solvers should reach the same solution if they all use the same mesh refinements, turbulence models and inputs. The verification of a solvers
