CFD analysis vs. internal ballistics

Click For Summary
SUMMARY

Computational Fluid Dynamics (CFD) analysis of the flow within a rocket's combustion chamber and nozzle is indeed relevant to the study of internal ballistics. Internal ballistics specifically addresses the gas pressure-driven transit of projectiles, while CFD provides insights into the fluid dynamics that influence this process. The discussion highlights the relationship between rocket engines and traditional firearms, emphasizing that while there are similarities, they should not be conflated. Understanding these distinctions is crucial for accurate analysis in aerospace engineering.

PREREQUISITES
  • Understanding of Computational Fluid Dynamics (CFD) principles

Apologies for the quick and dirty question, but I was wondering if a computational fluid dynamics analysis of the flow inside a rocket's combustion chamber and nozzle area would be regarded as an analysis of the chamber's/nozzle's internal ballistics. Looking up internal ballistics on wiki, it only gives a single line regarding rockets: "For rocket propelled projectiles, internal ballistics covers the period during which a rocket motor is providing thrust."

Any help would be appreciated

Interior ballistics refers to the gas pressure driven transit of a projectile inside a barrel.
Exterior ballistics is the non-powered external flight trajectory.

There may be an inverted similarity between a rocket engine and a cartridge fired in a chamber.
But how much do you want to confuse people by suggesting your rocket is inside a barrel?

Do you believe everything you read on wikipedia?
