This boundary defines inflow and outflow in the model; inflow occurring in the area when neighbouring nodes are at lower potential, while an effective gradient from neighbouring nodes defines the outflow from the model.
The swirling motion is generated by the rotating outer pipe of the annular air passage, thus providing well defined inflow conditions which can be easily reproduced in computational and modelling studies.
The vascular network consists of vessel segments connecting adjacent nodes on the lattice, with defined inflow and outflow nodes with prescribed pressures.
Three uncertain parameters that define the inflow profiles for velocity, turbulence kinetic energy and turbulence dissipation are defined: the velocity magnitude and direction, and the terrain roughness length.
There is a well-developed flap of skin in front of each nostril, defining the inflow and outflow openings.
However, training institutions differ in defining these inflow and outflow numbers, due to differences in starting dates and switching behaviour of students within and between training institutions.
Finally, we define the daily inflow of unprotected hosts U d by counting the number of recovered hosts who lose their temporary immunity conferred by the cellular protection (i.e. leave the C5 compartment) during day d, independently of the outcome of their humoral response.
Imbibition can be defined as the inflow of wetting phase and the displacement of non-wetting phase in the porous media under the forces of capillary pressure, gravity and buoyancy force.
The supply projection approach defines the necessary inflow to maintain or to reach in the future an arbitrary predefined level of service offer.
