SUMMARY

The discussion centers on the feasibility of using temperature differences to generate air currents for a sustainable house design. The user seeks to understand the necessary air temperature differential to create a strong pulling force through an opening in a glass roof. Initial experiments with a small model and a spotlight yielded no significant results, prompting inquiries about the definition of a "strong pulling force" in the context of air currents. The consensus indicates that a substantial temperature difference is essential for effective air movement.

PREREQUISITES
  • Understanding of thermodynamics and heat transfer principles
  • Familiarity with air pressure dynamics and buoyancy effects
  • Basic knowledge of sustainable architecture concepts
  • Experience with experimental modeling techniques
NEXT STEPS
  • Research the principles of thermodynamic airflow in enclosed spaces
  • Explore the impact of temperature gradients on air pressure and movement
  • Investigate materials and designs for effective passive solar heating
  • Learn about computational fluid dynamics (CFD) simulations for airflow modeling
USEFUL FOR

Architects, environmental engineers, and anyone involved in sustainable building design or airflow optimization in enclosed structures.

Dear physics forum, I'm currently working on a project and wondering what should the air temperature difference be to create a strong pulling force ? I'm working on creating a sustainable house, the concept is to have a enclosed glass roof with an opening that allows the sun to heat the air inside and as the contained air heats up, it will try to escape through the opening hence creating a pulling force, but my question is, is this even plausible? I tried it with a small model and a spotlight, doesn't seem to get any results tho. Need some opinion from you guys.

I am unclear on what you mean, or want, by a strong pulling force?

Do you want something akin to air currents?
 
So sorry that i did not clearly define my question, yes air current.
