This paper discussed the physics of inlet flows and, drawing on experimental studies, how to optimise inlet conditions. This includes decreasing the pressure drop at the inflow section and avoiding overpressure with a brick liner at the inlet. Tests on damper and turning vane systems show how to design them to improve the inlet flow and reduce pressure drop. A method to quickly mix the inlet gas to avoid hot spots was described and also an injector system for cooling hot gases.
The author stated that with such models it is quite straightforward to optimise inlet conditions, despite their apparent complexity. Calculation and computational methods are not able to provide such accuracy or reliability for this type of work.
