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

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?

Our team at CFDSUPPORT believes that success in engineering projects is the result of a combination of focus, skills, experience, patience, and dedication, rather than quick actions in a rush. To ensure accuracy, CFDSUPPORT regularly tracks and compares CFD results with real-world physical measurements. An example of our commitment to accuracy is the Centrifugal Compressor Benchmark project. This project was a collaboration between CFDSUPPORT and compressor manufacturer CZ a.s. The goal of the benchmark validation was to assess the accuracy of the TCFD software and compare its simulation results with actual compressor measurement data. By continuously striving for accuracy, CFDSUPPORT and its partners are able to deliver more reliable and trustworthy results for their clients.

please i would like to know how intall OPENFOAM with window software. i have downloaded the OPENFOAM logiciel on CFDsupport link

Hello Everyone, 

I am trying to simulate, bubble formation in two fluids, oil + water. How can I calculate the mass of the bubbles, formed in each phase?

Thank you 

In CFD we generally have a problem when we encounter something that is supposed to move on its "free will". One of these problems is an unknown rotation speed of a turbomachinery rotor. Common practice is that the user prescribes flow boundary conditions for one specific case or does a full spectrum of operational conditions including rotation speed. But what if he knows an input aerodynamic or shaft torque and wants to obtain a stable rotation speed (with no acceleration)?

One way is to use the TOPT algorithm where you look for a minimum of optimization function prescribed as (target_torque - calculated_torque)^2. 

First I calculated a torque for 187 RPM. Then I set this torque to our optimization function and ran TOPT with RPMs as a parameter.

After several runs, the RPMs started to converge around the value of 187 as they should. The DIRECT algorithm was still trying other options, but got to the minimum of our function relatively quickly.

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

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 ?

Dear Team, 

I am trying to run a simulation of the FDA Benchmark Blood Pump case with TCAE. I am using my meshes that I have generated by myself (not via TMESH). 

The project case setup seems to be fine, and I get the message "Project Setup OK" upon checking. However, when I start the TCFD run, I get the following error message after a while - 

"--> FOAM FATAL IO ERROR:

I do not know why this error occurs. Can you please help me out?

If required I can attach the case files as well. 

Thanks and Regards,
