Total pressure loss coeffcient
Nowadays, simulation models of steady and transient compressible internal flow are essential in analyzing devices and plants where piping systems for gases and steam are required, such as, pneumatic fluid power systems, transport piping systems, inlet and exhaust systems in alternating combustion engines and compressors. Models used in the simulation of steady and transient compressible flow in junctions require local total pressure loss coefficients. These coefficients can be experimentally obtained although a experimental support highly cost is required. Moreover, the internal flow behaviour is unknown. Alternatively, these coefficients can be obtained through numerical simulation using a 3D CFD general purpose software adequately validated. This work is aimed to numerical simulation of 3D steady compressible flow at junctions “T” type. The geometrical characteristics and the different types of mesh used during simulations will be described, as well as numerical schemes, turbulence ...
