Heat Transfer Calculation

Click For Summary
SUMMARY

This discussion focuses on performing a first principles heat transfer calculation for an ideal, monoatomic gas flowing through a stainless steel tube. The gas enters at temperature T and pressure P, with a small velocity v indicating laminar flow. The participant expresses difficulty in finding literature that provides a fundamental calculation of the heat transfer coefficient, h, instead of relying on empirical values. They seek resources or methodologies for conducting an ab-initio calculation, particularly at zero velocity.

PREREQUISITES
  • Understanding of heat transfer principles, specifically for gases.
  • Familiarity with laminar flow dynamics.
  • Knowledge of thermodynamic properties of ideal gases.
  • Basic proficiency in mathematical modeling and calculations.
NEXT STEPS
  • Research the fundamentals of heat transfer for ideal gases.
  • Explore methods for calculating heat transfer coefficients from first principles.
  • Study laminar flow characteristics in heat transfer applications.
  • Investigate ab-initio modeling techniques for thermal calculations.
USEFUL FOR

Engineers, physicists, and researchers involved in thermal analysis, particularly those focusing on heat transfer in fluid dynamics and gas flow applications.

I would like to do a first principles heat transfer calculation for an ideal, monoatomic gas at entry temperature T, and pressure P flowing at velocity v (v is small, so flow is laminar) through a stainless steel tube at some uniform temperature T' > T.

But if someone has done this calculation before, and I find it hard to believe that no one has, I'd rather just copy off them. :redface:

After some moderate searching through Mass & Heat Transfer books, I haven't found anything that doesn't use some literature value of the heat transfer coefficient, h. Where can I find a more fundamental calculation than that ? I will settle for an ab-initio calculation at v=0.

There are too many factors to make calculation of the heat transfer coefficient practical. We all resort to empirical numbers for such cases.
