Adolfo Delgado, Auteur ; Giuseppe Vannini, Auteur ; Bugra Ertas, Auteur |This paper presents the identification of the rotordynamic force coefficients for direct lubrication five-pad and four-pad tilting pad bearings. The bearing is 110 mm in diameter with a L/D of 0.4 pad axial length (44 mm). The experiments includ[...]

Adolfo Delgado, Auteur ; Luis San Andrés, Auteur |Squeeze film dampers (SFDs) aid to reduce excessive vibration levels due to rotor imbalance and to raise stability thresholds in rotor-bearing systems. SFDs commonly include end seals to increase their damping capability with a lesser lubricant [...]

Adolfo Delgado, Auteur ; Luis San Andrés, Auteur |In rotor-bearing systems, squeeze film dampers (SFDs) provide structural isolation, reduce amplitudes of rotor response to imbalance, and in some instances, increase the system threshold speed of instability. SFDs are typically installed at the [...]

Adolfo Delgado, Auteur ; Luis San Andrés, Auteur |Squeeze film damper (SFD) designs typically implement supply grooves to ensure adequate lubricant flow into the film lands. Oil seal rings, of land film clearance c, also incorporate short and shallow grooves (length

Luis San Andrés, Auteur ; Adolfo Delgado, Auteur |Oil seals in centrifugal compressors reduce leakage of the process gas into the support bearings and ambient. Under certain operating conditions of speed and pressure, oil seals lock, becoming a source of hydrodynamic instability due to excessiv[...]

Luis San Andrés, Auteur ; José Baker, Auteur ; Adolfo Delgado, Auteur |Brush seals effectively control leakage in air breathing engines, albeit only applied for relatively low-pressure differentials. Hybrid brush seals (HBS) are an alternative to resolve poor reliability resulting from bristle tip wear while also a[...]
