Example of inflow/outflow boundary conditions

This example is defined for a 2D geometrical configuration. The size of the domain is The flow is homogeneous (no multi-species gas) An inlet is located at the down left side of the domain. An outlet is located at the top right side of the domain. Conditions are constant in time

Example 2

Not for the release SUNFLUIDH_EDU

The flow is homogeneous (no multi-species gas) The temperature and the density are constant. The normal velocity component is time-dependent : The function is sinusoidal. The mean value of the time function is given by “Normal_Velocity_Reference_Value”. the frequency is 10 Hz The magnitude is 40% of the mean inlet velocity
