“…The contact forces were iteratively calculated with an FE model, taking into account the friction and deflection of the bristles. The frictional power was determined according to Equation (1). A constant friction coefficient of 0.24 was used.…”

“…The aim of the design process is to obtain a brush seal that is subject to minimal wear during operation, but it is still stiff enough to achieve the required pressure reduction in steady-state operation (see Ref. [1])). According to Aksit and Tichy [2], the wear of brush seals, similarly to other sliding contacts, depends on three ma in factors:…”

“…Leakage through a single stage brush seal is calculated using the formula for effective clearance as published in 1998 [6] . The effective clearance of brush seals has been established through testing and can be applied to estimate the leakage of any given fluid medium.…”

“…31 Recently, brush seals have been considered for retrofitting in industrial applications as stand alone or in combination with labyrinth seals. 44,45 There is an obvious need to explore suitability of brush seals for industrial turbines with a large utility combined-cycle since first experiences suggest that they can greatly improve the output power and reduce the heat rate. Retrofitting brush seals in a GE Frame 7EA turbine at a high pressure packing location demonstrated that a decrease in heat rate of 0.5% and an increase in the output power by 1.0% is achievable.…”

“…Retrofitting brush seals in a GE Frame 7EA turbine at a high pressure packing location demonstrated that a decrease in heat rate of 0.5% and an increase in the output power by 1.0% is achievable. 45 Over 200 brush seal installations in GE industrial gas turbines were reported. 27 The primary application areas are the high-pressure packing (HPP) at compressor discharge, the middle bearing, and the turbine interstage locations.…”
