Assembly Optimization for Double Row Ball Bearings
… is a treatise on optimal assembly methods for double row ball bearings. As with common single row bearings, double row ball bearings, consist of four general components, namely, an inner ring, an outer ring, a complement of balls and a cage or retainer to keep the balls separate. Unlike single …

A study of mechanical behaviour of the double-row tapered ring bearing for the main shaft of a direct-drive wind turbine
Double-row tapered roller bearings (TRBs) are one of the main components of a modern direct-drive wind turbines, TRBs are commonly used to support the main shafts of wind turbines since fault scan lead to the malfunctions and downtime of wind turbines. In recent decades, some numerical approaches …

Die Bedeutung des Kollagens für die Regeneration der Rotatorenmanschette: Histologische und immunhistologische Untersuchung der Verteilung der Kollagene Typ I, Typ II und Typ III nach single- und double-row-Naht-Anker-Rekonstruktion
… In neueren biomechanischen Studien zeigte die double-row-Naht-Anker-Rekonstruktion zur operativen Therapie der Rotatorenmanschettenruptur gegenüber der single-row-Technik bessere biomechanische Resultate. Das Ziel dieser Studie war die histologische und immunhistologische Untersuchung der …

Ab initio investigations of magnetic properties of ultrathin transition metal films on 4d substrates
… a novel magnetic ground state is predicted, a double-row-wise antiferromagnetic state along the [112] direction, a sequence of ferromagnetic double-rows of atoms, whose magnetic moments couple antiferromagetically from double row to double row. The magnetic structure can be understood as …

Cultivar, row spacing, and soil moisture effects on snap bean yield and morphological response to TIBA applications at early bloom
… acid (TIBA) at 1, 2, 4, 5 and 12 g/ha to field-grown snap beans (Phaseolus vulgaris L.) at early bloom caused a reduction in plant height and width but not dry weight. Yield differences occurred with the cultural variables of cultivar ('Sprite' and 'Dark-Seeded Provider') and row spacing (single …

Cooling hole geometry and turbulence effects on the early suction side surface of a turbine vane
… The fan-shaped geometries outperformed the double row cylindrical geometries with higher averaged film cooling effectiveness; but the fan-shaped geometries showed significant hole-to-hole variability. This behaviour was found at all turbulence intensities and most of the momentum flux ratios …

Heat Transfer Measurements and Comparisons for a Film Cooled Flat Plate with Realistic Hole Pattern in a Medium Duration Blowdown Facility
… the most common being a flat plate with a single row of cooling holes, have been run for decades and reported in the literature in literally thousands of papers. They have given valuable insight regarding the more fundamental aspects of film cooling, and the results of these works are used by the …

Development of a process modelling methodology and condition monitoring platform for air-cooled condensers
… for condenser cells and adapted to model double-row dephlegmators. A utility-scale 64-cell ACC system based in South Africa was selected for this study. The thermofluid network model was validated using site data with agreement in results within 1%; however, due to a lack of site data, the …
