Bluemira is an integrated inter-disciplinary design tool for future fusion reactors. It incorporates several modules, some of which rely on other codes, to carry out a range of typical conceptual fusion reactor design activities.
In advective_transport.py in _analyse_SN and _analyse_DN there is a corrective factor (f_correct_power) that should re-enter the tail of the exponential decay used to describe the power exhaustion within the scrape-off layer and ensure the energy conservation.
As such, this corrective factor would be expected to be an amount slightly greater than one. Instead this seems to be approximately 0.5 by effectively halving the first wall heat flux.
As the missing power to be re-entered comes from the flux that at the mid-plane falls outside the first wall, therefore unable to "carry" power by parallel transport, a way to correct the above mentioned factor and upgrade the broader heat flux calculation subject, is to perpendicularly distribute the missing power from the outermost flux line.
