Two glass plates, radiation and heat transfer?

Click For Summary
SUMMARY

This discussion focuses on calculating total radiation transmitted through double glazing consisting of two glass plates with an air gap, as well as determining total convective heat transfer across these plates. The user seeks to understand the heat loss due to forced convection and references the Nusselt number (Nu) as a function of Reynolds number (Re) and Prandtl number (Pr). A clear relationship between these parameters is essential for accurate heat transfer calculations in this context.

PREREQUISITES
  • Understanding of thermal radiation principles
  • Knowledge of convective heat transfer mechanisms
  • Familiarity with Nusselt number, Reynolds number, and Prandtl number
  • Basic principles of fluid dynamics
NEXT STEPS
  • Research the Stefan-Boltzmann law for calculating thermal radiation
  • Learn about the derivation and application of the Nusselt number in forced convection scenarios
  • Explore the relationship between Reynolds number and Prandtl number in heat transfer
  • Study double glazing design and its impact on energy efficiency
USEFUL FOR

Engineers, architects, and students in thermal sciences or mechanical engineering focusing on heat transfer analysis and energy efficiency in building designs.

Hey, how would I start solving the total radiation transmitted through one plate, an air gap then another plate (double glazing) as well as the total convective heat transfer across the two plates?

Thanks!

Also, how would I find heat loss due to forced convection? I know that Nu=f(Re, Pr), but I don't know how I would find the function that relates them? :S
