Nonadiabatic and frictional constant area duct flow: A visual software based simulation for compressible systems

Abstract

Numerical investigation of compressible flows in constant area ducts becomes substantially complicated when the surface roughness and heat flux conditions simultaneously act as independent and considerable boundary conditions that create significant influences on the now and heat transfer characteristics. This article presents GAS-DYN v 2.0, a specialized software package, capable of handling nonadiabatic and frictional systems with the contribution of a database, developed also by the author, which involves the real time temperature-dependent gas properties. Results of the presented computational analysis are in harmony with the available literature, which not only indicates the reliability of the package but also points out its adaptability to MSc and PhD level research studies and for the compressible flow system design projects.
