Multi-inlet with non-uniform widths

from mnflow.mfda.cad.dld.theme.block import DLD

  • You can adjust the width of each branch of inlet using the key width_nondim as shown in the following example. Note that:

    • The total width of inlet is used as a reference for nondimensionalization of width of each branch specified in width_nondim.

    • Width of each branch includes its sidewalls as well as its effective opening.

  • You can adjust the configurations of the extension segment of inlet via lst_config_extension as demonstrated in the following.

    d_c=5,
