Henry Selby Hele-Shaw

Henry Selby Hele - Shaw ( born July 29, 1854 in Billericay, † January 30, 1941 ) was a British engineer and professor at the University of Liverpool.

Hele - Shaw was a pioneer in the field of automotive technology and aviation. In 1922 he was president of the Engineers' IMechE ( Institution of Mechanical Engineers), which is comparable to the German Association of German Engineers ( VDI).

According to him, the Hele -Shaw cell is named, which is another of two (usually transparent ) plates at a small distance, which can be observed taking place in flow and bulk operations. In rheology is the generalized Hele -Shaw flow model (GHS - generalized Hele - Shaw flow model ) is used for describing the flow between two plates. Software for simulating fluid dynamics in thin areas (such as filling operations in injection molds ) offer in addition to the 3D volumetric calculation often also the less accurate, but computationally load- friendly 2.5 D Hele Shaw flow model.

In 1924, he improved the automatically adjustable aircraft propeller, which is also known as Hele -Shaw propeller. Although at this point the acceptance of this new technology was not very large, this concept has prevailed 20 years later in aviation, but also in other areas.

Hele - Shaw said to have been an avid mountaineer and with Sir David Randall Pye (1886-1960), who in 1952 also was President of the IMechE, have made first ascents. The latter was the biographer and friend of George Leigh Mallory, who died in 1924 while attempting to climb Mount Everest, far from the peak.
