Baffle dialog-Baffle Surface Properties tab

The Baffle Surface Properties tab of the Baffle dialog is used to specify the geometrical and thermal properties of the baffle.

Dialog elements

Diameter

Enter the required diameter for this component.

Heat transfer effectiveness

Specifies the heat transfer effectiveness (HTE) of the baffle. A HTE value of 1 (default) represents maximum heat transfer, a value of 0 represents no heat transfer.

Channel roughness

Specifies a relative channel roughness, defined by the thickness of the roughness relative to the diameter. If the value is left blank, the default value is used.

The relative channel roughness, along with the Reynolds number, is used to calculate the friction factor which is then used to calculate the pressure drop in the circuits. If the pressure drop is specified, the Reynolds number will be calculated using the relative channel roughness value. The relative channel roughness is also used in the boundary condition for the thermal equation of the Cool analysis.
