Heat radiation between two non-parallel surfaces

Click For Summary
SUMMARY

The discussion focuses on calculating heat radiation between two non-parallel surfaces, emphasizing the importance of view factors in this context. Tina inquires about formulas for determining view factors for surfaces oriented at angles between 0 and 180 degrees, as existing resources primarily address parallel and perpendicular configurations. A reference to a thermal radiation table is provided, suggesting that established methodologies exist for more complex geometries.

PREREQUISITES
  • Understanding of thermal radiation principles
  • Familiarity with view factor calculations
  • Knowledge of geometric configurations in heat transfer
  • Basic proficiency in using thermal radiation reference tables
NEXT STEPS
  • Research advanced view factor calculations for non-parallel surfaces
  • Explore the use of thermal radiation tables for complex geometries
  • Study the impact of surface orientation on heat transfer efficiency
  • Learn about software tools for simulating thermal radiation scenarios
USEFUL FOR

Engineers, physicists, and researchers involved in thermal management, heat transfer analysis, and those seeking to optimize thermal radiation calculations in complex geometries.

Hi everybody,

How do you find the heat radiation between two surfaces that aren’t perfectly parallel or perpendicular to each other?

I know that the view factors play a part, however, I can only dig up view factors for parallel and perpendicular surfaces:

Is there a formula for finding the view factor and thus the radiation between surfaces between 0-180 degrees?

Many thanks,

Tina
