Example of inflow/outflow boundary conditions
- This example is defined for a 2D geometrical configuration. The size of the domain is $1.5 \times 1.0.$
- 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
Inflow data
Example 1
- The flow is homogeneous (no multi-species gas)
- Conditions are constant in time
&Inlet_Boundary_Conditions Type_of_BC= "INLET", Direction_Normal_Plan= 1 , Plan_Location_Coordinate= 0.0 , Start_Coordinate_of_First_Span = 0.0, End_Coordinate_of_First_Span = 0.5, Start_Coordinate_of_Second_Span= 0.0 , End_Coordinate_of_Second_Span= 0.0 , Flow_Direction= 1 , Normal_Velocity_Reference_Value= 1.0 , Temperature_Reference_Value= 293.0 , Density_Reference_Value= 1.2, Define_Velocity_profile= 0 , End_of_Data_Block= .true. /
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
