Seeking help with Aspen Cycle Logistics
Thread Content
Dear experts, I am currently working on simulating lithium bromide absorption refrigeration systems, which involve circulating flow. I understand the concept of turbulent flow, but I’m not sure which option to choose. Do any of you have relevant materials that you could share? I’m currently studying Chapter 13 from Teacher Sun Lanyi’s textbook, but I still find it quite confusing. Thank you very much
There’s no need for tearing; use a shunt module.
The name “tear flow” sounds complicated, but it’s actually just Aspen helping to break the process apart. In cases like this where there’s no need for a closed loop, you can manually terminate the cycle after heating with steam
Have you done any simulations related to refrigeration, expert? I’m using a hot water type. I was wondering: when it comes to heating the water, should I set the temperature of the heater directly to the desired hot water temperature, or do I need an additional unit for that purpose? Thank you, thank you
Hello, could you be more detailed?:
Tear flow streams are used in the iterative calculations of the sequential modular method; generally, Aspen sets them automatically. If you understand how the sequential modular method converges and can set appropriate initial values to accelerate convergence, then you can set them manually. Since you probably don’t know that, it’s better to let it be automated
