SUMMARY

The discussion centers on finding the NTU (Number of Transfer Units) equation specifically for counter flow plate heat exchangers. Henrik Jakobsen initiated the conversation, expressing difficulty in locating relevant equations in textbooks. Respondents provided useful resources, including a PDF from the University of Thessaly and a paper from AIDIC, which contain the necessary NTU equations for plate heat exchangers.

PREREQUISITES
  • Understanding of heat exchanger principles
  • Familiarity with NTU effectiveness method
  • Basic knowledge of plate heat exchanger design
  • Access to academic resources or engineering databases
NEXT STEPS
  • Review the NTU equations in the provided resources from the University of Thessaly and AIDIC
  • Study the effectiveness NTU method in detail
  • Explore design considerations for counter flow plate heat exchangers
  • Investigate software tools for heat exchanger design simulations
USEFUL FOR

Engineers, thermal system designers, and students involved in heat exchanger design and analysis will benefit from this discussion.

Hi

I am woking on a project with dimensioning a plate heat exchanger and are looking at the effectiveness NTU method. The textbooks provide NTU equations for many kinds of heat exchangers but not for plate heat exchangers.

Does anyone knows where I can find an NTU equation for a counter flow plate heat exchanger?Best regards

Hello Henrik, welcome to PF :smile: !

I googled around and found http://www.mie.uth.gr/ekp_yliko/CEP_Plate_and_Frame_HX.pdf and http://www.aidic.it/escape20/webpapers/569Arsenyeva.pdf and a few more.
