Inflow boundary
WebKnown inflow boundary location In many problems the area, shape, and position of the inflow boundary are known a priori. For example, in the steady-state analysis of a forward extrusion process, an inflow Eulerian boundary can be used to model the flow of material into the adaptive mesh domain. WebThe numerical simulation of incompressible spatially-developing shear flows poses a special challenge to computational fluid dynamicists. The Navier-Stokes equations are elliptic and boundary equations need to be specified at the inflow and outflow boundaries in order to compute the fluid properties within the region of interest. It is, however, difficult to choose …
