Plate Heat Exchanger Sizing — ThermoFluidCalc

Configure Chevron plates stack parameters and check flows or size the stack count:

chevron Angle ($\beta$): Angle relative to vertical axis. Affects Nusselt and friction heavily.
Pressing depth ($b$): Spacing between plates forming flow channels.
Rating mode vs Sizing mode: Verify existing stack parameters or design the stack to fit target heat and pressure drop constraints.

Total Plates count ($N_{plates}$): Symmetric flow requires odd count (e.g. 11, 21, 31...)
