Air Properties for higher temperature.

Click For Summary
SUMMARY

This discussion focuses on determining specific air properties at elevated temperatures, particularly at 2550 Kelvin. Key properties requested include the Prandtl Number, Raleigh Number, scattering coefficient, absorption coefficient, specific heat, conductivity, thermal diffusivity, and thermal expansion coefficient. The conversation highlights that while 2550 Kelvin is a high temperature, air can still exist in a vibrationally excited state with minimal dissociation of nitrogen oxides (NO).

PREREQUISITES
  • Understanding of thermodynamic properties of gases
  • Familiarity with fluid dynamics concepts such as Prandtl and Raleigh numbers
  • Knowledge of heat transfer principles, including thermal conductivity and diffusivity
  • Basic concepts of molecular dissociation at high temperatures
NEXT STEPS
  • Research the calculation methods for Prandtl and Raleigh numbers at high temperatures
  • Study the effects of temperature on the scattering and absorption coefficients of air
  • Explore the specific heat capacity of air at elevated temperatures
  • Investigate the thermal expansion coefficient of gases under extreme conditions
USEFUL FOR

Researchers, engineers, and scientists working in fields related to thermodynamics, fluid dynamics, and high-temperature gas behavior will benefit from this discussion.

Welcome to PF... google: "thermodynamic properties of air"

...though that might be above the temperature at which air can exist.
 
If I remember right, that is still in the region air would exist. It would be vibrationally excited and maybe have a little bit of NO dissociation buy it would remain mostly air.
