Application of specific heat capacity ratio of air

Click For Summary

Discussion Overview

The discussion revolves around the application of the specific heat capacity ratio of air, particularly in the context of adiabatic processes such as those occurring in diesel engines. Participants explore its significance in various scenarios, including theoretical and practical applications.

Discussion Character

  • Exploratory, Technical explanation, Conceptual clarification

Main Points Raised

  • One participant mentions the importance of the heat capacity of air in adiabatic compression, specifically in diesel engines where the air heats sufficiently for fuel to ignite upon injection.
  • Another participant references the prevalence of the specific heat capacity ratio (denoted as \gamma) in compressible flow theory, suggesting its fundamental role in related calculations.
  • A request for clarification on the initial question indicates a need for more precise framing of the discussion topic.

Areas of Agreement / Disagreement

Participants have not reached a consensus on a specific application or example, and the discussion includes varying levels of understanding and requests for clarification.

Contextual Notes

The discussion lacks detailed definitions and may depend on specific assumptions related to thermodynamic principles and the context of air as a compressible fluid.

simple application please..o:)
 
Science news on Phys.org
The heat capacity of air is very important in adiabatic compression, like in a diesel engine. Adiabitic compression in a diesel engine heats the air to the point where the fuel burns immediately on injection. See

tnx Bob! great help!
 
Look at any text in compressible flow theory and you'll see [tex]\gamma[/tex] popping up all over the place.
