View Factor in radiation heat transfer

Click For Summary

Discussion Overview

The discussion revolves around the calculation of the view factor between two spheres in the context of radiation heat transfer. Participants explore theoretical approaches and seek resources related to the topic.

Discussion Character

  • Exploratory, Technical explanation, Homework-related

Main Points Raised

  • One participant inquires about the method to calculate the view factor between two spheres.
  • Another participant asks for clarification on whether the spheres are concentric and at uniform temperature, and requests information on how the original poster has approached the problem.
  • A third participant provides a reference to a solution from a textbook on thermal radiation heat transfer, suggesting it may be helpful.
  • Another participant requests access to a specific article by Howell regarding Monte Carlo strategies for radiative transfer, noting the unavailability of the book in their library.

Areas of Agreement / Disagreement

The discussion does not show clear agreement or consensus, as participants are exploring different aspects of the problem and seeking additional resources.

Contextual Notes

Participants have not provided specific assumptions or details regarding the configuration of the spheres, which may affect the calculation of the view factor.

Hi
can anyone temme how to calculate view factor between two spheres.
 
Engineering news on Phys.org
Are the spheres concentric and at uniform temperature? How have you tried to start this problem?

This migh be of any help

see attachment.

Solution by
Thermal Radiation Heat Transfer
Robert Siegel and John Howell

Reference: Juul (1976); Felske (1978); Chung and Naraghi; Grier; Campbell and McConnell; Farnbach; Jones

hi..can anybody send me the article of Howell R. "monte carlo strategies for radiative transfer in participating media" this is in a book but in our library, this book is not available...
