. Some thoughts on doing simulations
Thread Content
1. Foundations are important； All the seniors have mentioned topics such as chemical thermodynamics, principles of chemical engineering, property calculations, and fundamentals of chemical engineering calculations... Before conducting simulations, it’s necessary to first figure out what problems need to be solved, then list the available conditions, and then address those problems. It’s not worthwhile to carry out calculations just for the sake of simulation; doing so serves no purpose. 3. There are many models, but it is essential to understand the number of degrees of freedom in the calculations for each model; in order for such a model to converge, certain conditions must be met. For example, in the case of a heat exchanger with two streams, three known conditions related to temperature are required in order to solve the problem. 4. Conduct a thorough analysis and calculation for each module, especially the distillation tower. 5. The calculations related to distillation towers are quite complex; it’s essential to understand the conditions necessary for a tower to converge, as well as the priority of these conditions... Looking forward to everyone’s additional insights
5. Distillation column calculations are quite complex; it’s essential to understand the conditions necessary for a column to converge, as well as the relative importance of these conditions. This is very difficult – many experiments need to be conducted; if convergence doesn’t occur, then it simply doesn’t happen. Even when convergence is achieved, it’s not clear why it happened. The key is to figure it out on one’s own (since there’s no design institute providing guidance!) One word: Tired! There is no benefit yet…… :$
Hehe, I just realized that all three posts in a row are yours... How good are you? Teach my bro?
I’m just starting to learn simulation, and the original poster’s experience is very helpful for beginners! Thank you for sharing.
