ANSYS CFX smoke simulation

You want to know the components of the fluid and their proportionate amounts, right? Fluent works too

I just started learning*, and I’m working with CFX in Ansys Workbench; I don’t know Fluent

Learning it is too difficult; the difficulty lies not in the software itself but in the fundamental theories. I have been studying it for many years – at first I focused on learning how to use the software, and after some time I realized that my knowledge of the fundamental theories was insufficient, so I spent three years reviewing those theories. Only now have I almost mastered them. The gains have been significant, but now I find myself too lazy to use the software. In addition to the difficulty of the basic theory, another requirement is having sufficient engineering experience in order to make good use of this software. As a hobby, you can learn more about it; but if you want to apply it at work, it’s not necessary to master it thoroughly, as no one will be able to understand the calculation results or analyze and evaluate them. In domestic design institutes and research organizations, including a screenshot of FEA in a PPT is just a way to deceive people – don’t take it seriously; in reality, they don’t actually know how to use it! !

The purpose of learning this is mainly to conduct flow field simulations in certain specific areas, to check whether the airflow is distributed evenly; it serves primarily as a reference

In my personal opinion, it’s better not to learn it in this way; the finite element method is a systematic and interdisciplinary approach that cannot be applied in an incomplete manner. It is only meaningful to master the systematic theoretical knowledge and combine it with practical engineering applications. Otherwise, even if you can obtain some calculation results, not understanding why they were obtained will only lead to greater confusion! !

There seems to be an example of smoke diffusion in the Ansys help documentation; you can give it a look. Indeed, as mentioned above, it’s difficult to understand the calculation results, and their accuracy is also unknown. It’s hard to think of applying intelligence in engineering contexts (hehe!) ).

In the coking industry, it’s very rare, haha. . . . .

The finite element method and computer-aided design CAE represent the directions of development. The theoretical barriers in many technical fields were overcome a long time ago, but their implementation is difficult due to the complexity of the calculations involved. The rapid development of computer hardware and software in recent decades has, to a certain extent, addressed the issues of computing speed and accuracy, and their use in the field of engineering construction is set to increase further. However, the theoretical foundation of the finite element method is particularly crucial. High demands are placed on those who use this method, as much of the knowledge involved falls within interdisciplinary areas. Being able to assess and utilize the finite element method effectively and accurately remains a challenge. Due to the variability and complexity of the computational results, there is a significant disparity in people’s ability to interpret them in China; this is related to the quality of individuals. Additionally, the academic atmosphere in China is not very good, and the management systems are inadequate, with a top-down approach where the authority of those in charge is absolute. Under such circumstances, people tend to follow the opinions of their superiors and hesitate to express their own views, which also constitutes an obstacle to the development of the finite element method. This is true both in China and abroad, though foreign countries have more open academic research and management systems, allowing people to express their opinions freely, which is somewhat better than the situation in China Personal opinions are for reference only!
