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 flow and heat transfer characteristics. This article presents GAS-DYN v2.0, 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.

A pedagogical flight simulator for longitudinal airplane flight

“…Moreover, computer simulations can efficiently raise student's interest of learning by vivid graphical construction and animation [8,9] and be used to help students to gain insights into phenomena and overcome the mathematical difficulties [10].…”

Learning hydraulic turbomachinery with computational fluid dynamics (CFD) codes

“…We point out that several studies analyze the ability of CFD codes as a teaching tool in other flows of engineering interest as, for example, the analysis of a turbulent wake behind a cylinder 8, the cooling of electronic equipment 9, the analysis of a Venturi tube 10, the study of compressible fluids 11, hydrodynamic lubrication 12, etc. Furthermore, the complexity of a CFD code becomes suitable for developing several skills in combined projects (see, e.g., 13, 14).…”
