“…In recent years, some researchers have compliant foil sealing system installed in a small turbine engine simulator for performance tests, through the test study of compliant foil seal leakage, measurement found that, when the temperature is 20 • C, the differential pressure ratio is 6, the shaft diameter is φ72 mm, the rotor speed is 40,000 rpm, the measured leakage of the compliant foil seal for the brush seal leakage is about 30%. No serious contact friction and obvious wear phenomena were observed during the operation of the compliant foil seal [70,86], and this research result has not been tested by the harsh working conditions such as the actual large vibration displacement of aerospace gas turbines.…”

“…As a typical form of elastic floating seal, its main working principle is when the shaft is running steadily, due to the role of fluid dynamic pressure effect, resulting in a thin layer of fluid film, sealing the element metal sheet in the fluid film to realize the elasticity of floating, which can effectively reduce the static parts and rotating parts of the sealing vice of the friction between the scraping, touching abrasion, wear and tear. At the same time, this new type of seal structure design is more compact, can be realized by compliant support to control the seal shaft having a certain radial displacement (radial displacement within 0.381 mm) [70][71][72].…”

“…Under high parameter conditions, the real fluid effects of a DGS are highlighted. The assumptions such as ideal gas, laminar flow model, and forced pressure boundary condition in the traditional design may no longer be applicable [3,4]. In recent years, many scholars have studied the influence of real fluid effects in the DGS.…”
