Volume 14, Issue 2 , June 2021, , Pages 1-26

Abstract
  In this paper, the heat transfer and ablation thermal insulators in solid rocket motor are investigated. Therefore, by collecting and solving the thermal ablation equations, a computer program, using MATLAB software, is developed which can predict the thermal response of insulators in different operating ...  Read More

Numerical simulation of complicated grains with 3D burnback and Quasi-One-Dimensional flow field of solid rocket motors

mohammad shahbazi; mohammad razmjooei; Fatholah Ommi

Volume 12, Issue 2 , September 2019, , Pages 23-41

Abstract
  In this research, the 3D grain burnback with quasi-one-dimensional internal ballistic in a solid rocket motor is simulated using the Level set theory and the utilization of Sections method, while achieving high accuracy in the simulation of green's post-back analysis time can also be significantly reduced. ...  Read More
