HHFtools is a set of modular calculation tools written in Python3 which can be used to provide first order estimates of thermofluid performance including convective heat transfer and pressure drop for simple high heat flux components. Heat transfer coefficients are calculated using the same set of equations as has been used for ITER divertor and first wall design with parameters for simple tubes, swirl tape inserts, rectangular channels, and hypervapotrons. Similar tools are partially developed for pin-fin arrays and multiple small channels in parallel.
