Centrifugal fan design & simulation, an overview of complex virtual prototyping of centrifugal fans using Computational Fluid Dynamics (CFD), Finite Element Analysis (FEA), and Fluid-Structure Interaction (FSI). These technologies offer engineers a comprehensive toolset to design, optimize, and analyze the performance, structural integrity, and reliability of centrifugal fans.

With the use of CFD, engineers can simulate and analyze the fluid flow inside the fan, allowing them to optimize the geometry, blade angles, and other design parameters for maximum efficiency and performance. Additionally, FEA can be used to analyze the structural integrity of the fan, ensuring it can withstand the forces and stresses generated by the fluid flow. FSI combines the analysis of fluid flow and structural response, allowing engineers to understand how the fan structure will deform under the influence of fluid forces.

The combination of these technologies enables engineers to simulate and optimize a variety of scenarios, including different operating conditions, such as varying fan speeds, flow rates, and fluid properties. This allows engineers to refine the design of the fan before building a physical prototype, reducing development costs and improving the overall performance and reliability of the fan.

In this overview, we will explore the benefits of using CFD, FEA, and FSI to design and optimize centrifugal fans. We will also cover the basic principles of each technology and how they can be used in combination to simulate and analyze the performance and structural integrity of centrifugal fans. So, let's dive in and explore the world of virtual prototyping of centrifugal fans using CFD, FEA, and FSI!

Beam Ball FS Benchmark. 

TCAE is a simulation environment for comprehensive CFD, FEA + FSI, and optimization in a single workflow. Take a look at the study of the Beam-Ball FSI benchmark. This study is unique, because the exact solution can be evaluated analytically, and the analytical solution can be compared with the simulation results. The particular goal of this study is to investigate and compare the deformation of a beam with a ball at its end, stressed by the airflow.

Hello! Everyone, 

I was looking at a video about acoustics and there I saw that the virtual microphone data is converted into an audio file which I thought was incredible. Please if anyone knows how this can be done in OpenFOAM or TCAE? 

Thank You

We are currently running ubuntu v18.04 and TCAE version v23.03.  We are now adding a second server node to start building an HPC 2 node cluster.  We are thinking to upgrade ubuntu at this time. Is ubuntu v22.04 supported with TCAE v23.03, or should we stay with ubuntu v20.04 as this is the most current version that is mentioned in the TCAE software manual.

Hi everyone!

I want to call a tensorflow neural network while running TCAE redSolver.

Is there any relevant tutorial available?

Thank you!

Hi, I am trying to use TCFD for distributed computing on the high performance computing platform of my own department. This platform uses slurm as the job scheduling system. When I use the command: `srun -n 127 -N 10 -p normal redDyMSolver -rotatingVelocityFields -parallel`, the error shown in the picture occurs.

I am not sure if it is a problem with the high performance computing platform or with TCFD. Can anyone help me?

Or is there any other way for me to perform distributed computing with TCFD on the high performance computing platform?

Axial Turbine Stage - test topic. Axial Turbine Stage CFD. It is hard not to be emotional when seeing an axial turbine stage CFD. The axial turbine stage was our first big CFD project made here at CFDSUPPORT. In a way, it had preset our destiny - turbomachinery simulations. Here is a little example of how now, ten years later, TCAE runs the whole complex process in one command (or click). By TCFD: https://www.cfdsupport.com/axial-turbine-cfd-simulation.html

Hello,

I'm trying for the first time to use the "Add hosts" feature which, if I understand correctly, allows us to use computing cores on machines that are on the same network as ours.
So I try to add a host whose IP is for example 192.168.0.150, whose username is User1 and which has 4 cores. On my machine, for example, I want to allocate 8 cores for the calculation, i.e. a total of 12 cores. Both our machines are Linux machines.
1) I have already sent him my public authentication key id_rsa.pub so that I can connect to it without entering a password with
2) I have already installed on this machine the same version that I use of TCAE (23.03v3)
3) I also run source $HOME/TCAE/TCAE-23.03v3/OpenFOAM-dev/etc/bashrc-release on machine 192.168.0.150
However, on the GUI, the info tells me that the host is not known. What did I miss?

Thanks for your help

In this new version of TCAE 23.03v1, the command mode

echo $OPTION > $TCAEproject/cfdp-command.txt
kill -SIGINT $TCAEpid

doesn't work. I guess due to the several changes in all TCAE project repertories, the file cfdp-command.txt has also change. Probably the name, it format or it location?

Hello everyone,
I'm having a problem with a value (Cp: specific heat) that I want to set as default in all my TCAE projects. For that I modified the file TCAE-23.03v1/TCAE/etc/CAEProcessorDefaults.tcae by adding
Cp "1800_J/(kg.K)"
When I create a new TCAE project, the value of Cp is well defined at 1800 J/kg/K. However, it seems that when through the GUI I set the value to 0

and that I save, restore then check, no error is reported and I can run the simulation without any problem. That's when I looked at the TCAEproject/setup file and I was surprised to see that the heat capacity value was changed to
Cp "1004_J/(kg.K)"
This value corresponds to the air, originally set by default in the CAEProcessorDefaults.tcae configuration file.

So why my value that I set to 1800 J/kg/K was not returned ?

Hello,

I would like to present my current project for further experiments with TCAE and TOPT.

It is a parametric axial fan created in the OpenVSP free parametric CAD primarily used for aviation purposes. It allows controlling the geometry with pre-programmed parameters and their further linking. It can also be controlled by external scripts. All these functions are perfect premises for geometry optimization with our TOPT module.

This model is designed for catalogue-like making of fans for defined conditions. You create a spectrum of axial fan variation and then choose which one suits the best (with consideration on parameters like pressure drop or aerodynamic torque and then fan efficiency calculated from them).

Simplified model will be used in the upcoming TCAE tutorial, where only a few basic blade parameters will be modified. Its main purpose there will be demonstration of the TOPT capabilities and their potential use in industrial design.

Hello everyone,

I have seen that it exists a new option called --apply-diff for the CAEProcessor command. The help just said that it "changes the project setting by specifying the path to the text file with TCAE configuration keywords, which are to be changed." And the example give us only

CAEProcessor --project fan --apply-diff changes.txt --save-as fan-2

But I wonder what is the information and format of this changes.txt file?

Hello everyone,

I have just installed the new version 23.03v1.

I wonder in which cases it is necessary / recommanded / relevant to enable "Use external geometries / meshes (file will not be imported into the project)" in TMESH in this new version 23.03v1 ? I have noticed that in TCAE/tutorials repertory, it is enable only when TOPT is used.

In my case I have got an already meshed geometries from FLUENT but I have seen that it is possible to both enable/disable this feature. But I have encountered some issues when it is disabled. More specificaly, sometimes, when I restore the project, one interface (inlet/outletInterface) disappear.

What do you recommend?
