There were three types of spacers instrumented along the axial length in the PSBT facility: simple spacer (SS), spacer with no mixing vanes (NMV), and spacer with mixing vanes (MV). The simple spacer has only dimples while NMV and MV have dimples and springs. The benchmark provides the bundle average spacer pressure loss coefficients for the three types of grids. Depending on the participants’ computer code, and using the provided spacer data, each participant may choose the sub-channel grids loss coefficients or other required input values.

Apply the pressure drop due to the concentrated loss coefficients at the correct _z_grid locations in our momentum equation. Axially varying the turbulent mixing coefficient is also a possibility we could look into.
