Problem Description

A projectile weighing 120 grams is initially at rest inside a 20 mm caliber barrel. The gas inside the chamber is patched at a high pressure of 3000 atm and a temperature of 2700 K and the projectile is released

The motion of the projectile is computed using a UDF based on FLUENT’s Six Degree of Freedom UDF. In this case, only the pressure forces are considered, while drag and mechanical friction are neglected. The projectile is released at t=0. The Abel-Nobel equation of state is implemented using the user-defined real gas model
