Thermal Hydraulics: Connect with Experienced Researchers

Click For Summary

Discussion Overview

The discussion centers on thermal hydraulics, particularly the use of various thermal-hydraulic computer codes such as RELAP5, TRACE, RETRAN, and others. Participants share their experiences and seek collaboration on studies related to thermal hydraulics, including applications in safety analysis and fluid dynamics.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested
  • Homework-related

Main Points Raised

  • Some participants inquire about the use of thermal-hydraulic computer codes and express a desire to share experiences related to RELAP5 and TRACE.
  • One participant mentions using TRACE and expresses interest in connecting with others for experience sharing.
  • Another participant discusses their indirect work with thermal hydraulics, noting its importance in establishing thermal boundary conditions and mentioning various codes like RELAP, RETRAN, and computational fluid dynamics tools such as FLUENT and CFX.
  • A participant shares their limited experience with RELAP and RETRAN, detailing their work with PIPEFLOW, GOTHIC, and other methodologies for pressure and temperature calculations.
  • Some participants seek information about thermal hydraulics courses, indicating a desire for educational resources in the field.

Areas of Agreement / Disagreement

Participants express a general interest in thermal hydraulics and share various experiences with different codes, but no consensus on specific methodologies or approaches is reached. Multiple competing views on the use of different codes and their applications remain evident.

Contextual Notes

Some discussions may depend on specific definitions of thermal hydraulics and the context in which various codes are applied. Limitations in participants' experiences with certain codes may affect the depth of discussion.

Who May Find This Useful

Researchers and students interested in thermal hydraulics, safety analysis, and computational fluid dynamics may find this discussion beneficial for networking and sharing insights.

hi guys

does anyone work on thermal hydraulics? I'm currently doing studies based on both RELAP5 and TRACE codes and i would appreciate if we can share our experiences
 
Engineering news on Phys.org
does anybody use any thermal-hydraulic computer code?
 
I work with thermal hydraulics indirectly since T/H forms the thermal boundary conditions for some of my work.

RELAP is one code used in safety and licensing analysis. Many utilities use RETRAN (and EPRI sponsored code) and VIPRE, and over the last decade or so, the industry has been increasing the use computational fluid dynamics with codes like FLUENT, STAR-CD and CFX.

In addition to T/H, turbulence and fluid-structure interaction (FSI) are being studied in much greater detail.

Hi drsenbei,

I also use TRACE. Are you still interested in sharing experiences?

kind regards,

There's a new 3-day course June, 2011 in Columbia, Maryland. I'm excited! Here's the link to ISL's RELAP5 User Workshop: http://www.islinc.com/training/"

My experience with RELAP and RETRAN has been limited to reviewing annalyses prepared by others. Similar experience with GE's SHEX code. I have worked with PIPEFLOW and performed complete pressure/temperature/humidity calculations with GOTHIC in support of room heatup calculations for Station Blackout and High Energy Line Breaks. I have done some work with BOP Heat Balances using PEPSE. Finally I have performed fluid flow calculations using the methods in Crane TP-410 and using experimental data for flow resistance prepared by I. E. Idel'chik. In a similar methodology I have performed radiological source term transport and dose assesments usingn RADTRAD and spreadsheet methods.
