Experimental Hypersonic Aerodynamics and Advances in Aerospace Engineering

Shahed Malekipour; Mohammad Ebrahimi

Volume 1, Issue 1 , September 2017, Pages 1-10

Abstract
  Most space missions fall in the hypersonic reentry regime. There are several open questions and unknown phenomena in aerothermodynamics around vehicles at flow regimes exceeding Mach 4 due to its inherent complexities. Strong entropy gradients, thick shock layers, dissociated high temperature flows, ...  Read More

Shahram Ghorbanifar

Volume 1, Issue 1 , September 2017, Pages 11-18

Abstract
  Due to the complex nonlinear nature of Navier Stokes equations, theyhave not yet been fully solved ad hencethe role of classical CFD methods have become more highlighted. Using numerical methods, we can discretise nonlinear partial differential equations and change them into linear algebraic equations ...  Read More

Trapped-Vortex-Combustor: a Novel Technology in the Gas Turbines

Mostafa Esmaeili

Volume 1, Issue 1 , September 2017, Pages 31-41

Abstract
  In the present study, the evolution of using TVC as a novel technology in gas turbine combustors is investigated. The reported data suggest that different types of TVCs (AFRL and GE products) havethe potential toprovide low lean-blow out (LBO) and a wide range of dynamic operations. Also, in some types ...  Read More
