Store Separation from a 3D Delta Wing - دینامیک مش شش درجه آزادی

Introduction
This tutorial illustrates the setup and simulation of store separation from an airplane wing.The
flow is inviscid and compressible. The objective of this simulation is to model the motion of the store using the Six Degrees of Freedom (6DOF) solver in FLUENT. The results of the FLUENT simulation are compared with the results computed from a series of wind tunnel tests. For the details about the wind tunnel testing, refer to Appendix. This tutorial demonstrates how to do the following

  Use the DEFINE SDOF PROPERTIES macro to specify the mass matrix and any external forces/moments

 Use the dynamic mesh (DM) feature in FLUENT

Set up a compressible, transonic flow (Mach 1.2) in FLUENT

Set the boundary conditions

 Set up dynamic adaption

 Obtain a first order solution using the density-based implicit solver

Solving a 2D Vibromixer Problem Using the Dynamic Mesh Model - دینامیک مش - ویبرومیکسر

Introduction
The dynamic mesh model in FLUENT can be used to model flows where the shape of the domain is changing with time due to motion on the domain boundaries. The motion can be either a prescribed motion (e.g., you can specify the linear and angular velocities about the center of gravity of a solid body with time) or an un-prescribed motion where the subsequent motion is determined through a user-defined function
The update of the volume mesh is handled automatically by FLUENT at each time step
based on the new positions of the boundaries. To use the dynamic mesh model, you need
to provide a starting volume mesh and the description of the motion of any moving zones
in the model
This tutorial demonstrates the use of FLUENT's dynamic mesh capabilities for a vibromixer a device with a perforated (cylindrical) plate of small thickness that moves with a sinusoidal motion which is implemented through a UDF

Transonic Flow over a NACA 0012 Airfoil - جریان گذرصوت روی ایرفویل

The purpose of this tutorial is to introduce the user to good techniques for modeling flow in high speed external aerodynamic applications

Transonic flow will be modeled over a NACA 0012 airfoil for which experimental data has been published, so that a comparison can be made. The flow to be considered is compressible and turbulent .The solver used is the density based implicit solver, which gives good results for high speed compressible flows

The tutorial is carried out using FLUENT and CFD Post from within Workbench, but it could also be completed in standalone mode

Modeling of Catalytic Convertor - porous media - محیط متخلخل

A workshop to demonstrate how to model porous media in FLUENT

Workshop models a catalytic convertor. Nitrogen flows in though inlet with an uniform velocity 22.6 m/s, passes through a ceramic monolith substrate with square shaped channels, and then exits through the outlet. Substrate is impermeable in Y and Z directions, which is modeled by specifying loss  coefficients 3 order higher than in X direction

جریان تراکم پذیر بر روی یک توربین آبشاری - Compressible Flow over a Turbine Cascade

Introduction

The purpose of this tutorial is to provide guidelines and recommendations for solving a real world CFD problem which includes

 Building the geometry and generating a mesh in GAMBIT
 Setting up the CFD model in FLUENT
Solving the problem and comparing the results with the experimental data

The problem is to predict the performance of a highly-loaded linear transonic turbine guide vane cascade. The experimental measurements were performed at the Von Karman Institute for Fluid Dynamics

Problem Description

The schematic of the problem is shown in Figure. The linear cascade consists of 5 blades. The central blade is instrumented for data measurements and is also the focus of this numerical simulation. The incident flow angle to the cascade is 0 degree. Isentropic Mach number at the outlet is 0.84, and outlet Reynolds number is 1e6. The boundary conditions of total pressure, total temperature, turbulence intensity are

143500 Pa	Total Pressure-absolute
300 K	Total Temperature
5 %	Turbulence Intensity
12 mm	Turbulence Length Scale

Static pressure at the outlet is 90405 Pa. Periodicity of the flow through the cascade allows
the use of periodic boundary condition along the top and the bottom sides of the domain surrounding the central blade
