Numerical Study of Transverse Injection into Supersonic flow of the Scramjet Combustor

Mostafa Zahedzadeh; Fathollah Ommi

Volume 2, Issue 1 , June 2018, Pages 1-8

Abstract
  Nowadays efforts for development of the scramjet engines are increased. Scramjet engines use atmospheric oxygen as an oxidizer therefore they don’t need oxidizer tanks, thus the weight of these systems is less than comparable rocket systems. Success of the air-breathing engines depends on the proper ...  Read More
