An investigation of flow characteristics between different mediums

Abstract In this research topic, two-dimensional tunnels made of different mediums (including the contrast gas-solid condition and solid-solid with or without a bump) are designed to compare how they influence velocity pressure fluid when is flowing through them. The Navier-Stokes momentum equation used guide project set up equations motion for these models. At same time, Newton’s law viscosity applied boundary conditions. Numerical methods involving finite differences help discretize those simulate models in computers. result shows that influenced significantly by settings. A nozzle bump can also affect fluid. As materials change, dependence flow characteristics terms x y-direction will shape tunnel traits.
