Gerhard Dickel

Gerhard Dickel (28 October 1913 – 3 November 2017) was a German chemist and physicist. He developed a thermal diffusion method of separating isotopes with Klaus Clusius in 1938, sometimes referred to as Clusius-Dickel separation. thumb|In this version, the fluid with different isotopes is contained in the annulus under optimal conditions, undergoing convection in the temperature gradient between the walls.

The central cavity within the inner wall might contain hot water with the exterior of the outer wall jacketed in cold water, for example. The process can also use a flat-plate cell instead of an annulus.
