Cavities formed by discs contained within a shroud, either of which may be rotating, are a common feature of turbomachinery
The purpose of this data is to provide an understanding of the flow in cavities, an introduction to generalised analysis and to describe the role of Computational Fluid Dynamics as the principal flow-analysis tool currently used for such flows.

New Data – Stress Concentration Factors for optimised holes in flat plates
ESDU 15005 considers the optimisation of the shape of typical holes found in structural components to significantly reduce the peak elastic stresses around the hole, as well as to increase the fatigue life of the component under a given set of loading and geometry conditions. Finite element ana... Read more...More Product Announcements from IHS ESDU

Tyre in Linear Motion on a Runway Covered by Various Forms of Loose Snow
This data demonstrates the application of an empirical model in order to calculate the retarding forces acting on an aircraft-type tyre that operates in a braked state on a runway that is covered by a layer of loose snow.
Decelerating forces are calculated for a wide range of operating speeds an... Read more...More Product Announcements from IHS ESDU
The optimisation of the design of a DIN 6885-1 keyway
This data considers the effect of key and keyway design on the stresses in a keyed shaft loaded in torsion, bending or under combined torsion and bending. Common types of keys, such as the Woodruff key and the square key are discussed and stress concentration data is given for a range of keyway geometries for both the sl...
