Julius Hartmann and His Followers: A Review on the Properties of the Hartmann Layer

Part of the Fluid Mechanics And Its Applications book series (FMIA, volume 80)

Julius Hartmann, born in 1881 (November 11th) and deceased in 1951 (November 6th), was a leading Professor at the Technical University of Denmark, in Copenhagen, where he founded the Laboratoriet for teknisk fysik, which was the basis for today’s Department of Applied Physics. In this laboratory, he worked on different technical processes, inventing in particular the device now called the electromagnetic conduction pump to drive the flow of electrically conducting liquids, such as molten metals. He may be the first scientist using mercury in a hydraulic circuit, and applying a magnetic field and a DC current in two orthogonal directions, both perpendicular to the duct axis, to generate an electromagnetic force capable to drive a fluid flow against friction. In the archives of the Copenhagen Technical University, there are still reminiscences of this pump, whose construction dates back to probably 1915–1917. But it is now extremely difficult to get published papers related to this pioneering work (Moerch [1]).
