In industrial CFD consulting, my company has found the “Mean Age of Air” concept to be incredibly useful. It helps leverage a steady-state solution to show some transient-like flow behaviors. The steady-state solution already has characterized the primary and secondary flow structures, so adding in the Mean Age of Air calculation can enable some time-based information to be gleaned from the solution. We also have noticed that the concept is not well-documented in the CFD community, so we put together a workshop on how to incorporate this calculation into your CFD predictions. The workshop is also a great overview on convective vs. diffusive driven flow, so if you are a CFD beginner, it’s worth a listen. A summary and how-to steps are also available here: https://www.azorecfd.com/blog/mean-age-of-air Some applications: - Tank purging/cleaning operations - Ventilation of enclosed spaces - Air exchange rates in HVAC models - Identification of stagnant/bypass flow

In this post I will detail how to clean CAD geometry in writing. Attend the event for the live demonstration. 1.) in the right hand panel click on the eye icon for all the geometries except the one you want to edit 2.) click on the geometry you want to edit and go into edit mode 3.) go to select > select by trait > non-manifold edges. When you do this all the non-manifold edges will be highlighted. Use this to locate them. 3.5) you can also use x-ray to see through the geometry 4.) upon sighting the non-manifold select all the nodes/edges encasing the hole by holding ctrl + clicking 5.) press F to create a patch Repeat steps 1-5 to have satisfactory watertight geometry

Hello, CFD Enthusiasts and Aspirants, I have a plan to collect real-time CFD interview questions here to help you land your dream job (I'm also searching for a job). You can post your questions and answers here, which will definitely help someone with their job interview. The availability of CFD Q&A on blogs and other sources may be outdated. This platform will help us stay updated and learn how to answer questions logically.

I am starting this thread to teach anyone how to use it. Starting with virtual private cloud. A virtual private cloud network is a private cloud network that is owned by you, an alibaba cloud user: 1.)log onto console 2.)navigate to virtual private cloud 3.)name your vSwitches based on their regions, ensure the ip addresses don't overlap (2 vSwitches having the same IP address) edit note: VPCs aren't expandable, once you have created one you can reuse it indefinitely forever.

In this post, I want to share two files about CFD Vision 2030 Roadmap Progress and Technology Highlights for 2022. I won't explain it and if we read these files, it can help us to plan what we need to learn for the future. It describes the direction of movement and development in the specialized field of Computational Fluid Dynamics. I think it will be very helpful for anyone in the field of CFD, in any level of working.
