Electromagnetic forming (EM forming or magneforming) is a type of high-velocity, cold forming process for electrically conductive metals, most commonly copper and aluminium. The workpiece is reshaped by high-intensity pulsed magnetic fields that induce a current in the workpiece and a corresponding repulsive magnetic field, rapidly repelling ...
An explosively pumped flux compression generator (EPFCG) is a device used to generate a high-power electromagnetic pulse by compressing magnetic flux using high explosives. EPFCGs are physically destroyed during operation, making them single-use. They require a starting current pulse to operate, usually supplied by capacitors.
Figure 1: Schematic drawing of a Stirling-type single-orifice PTR. From left to right: a compressor, a heat exchanger (X 1), a regenerator, a heat exchanger (X 2), a tube (often called the pulse tube), a heat exchanger (X 3), a flow resistance (orifice), and a buffer volume. The cooling is generated at the low temperature T L. Room temperature ...
The magnetocaloric effect can be quantified with the following equation: = ((,)) ((,)) where is the adiabatic change in temperature of the magnetic system around temperature T, H is the applied external magnetic field, C is the heat capacity of the working magnet (refrigerant) and M is the magnetization of the refrigerant.
The term is most often used for smaller systems, typically table-top size, with input powers less than about 20 kW. Some can have input powers as low as 2–3 W. Large systems, such as those used for cooling the superconducting magnets in particle accelerators are more often called cryogenic refrigerators. Their input powers can be as high as 1 MW.
PCD-system operates in the following way: The crankshaft 4 starts moving in a circular motion by the external drive. During the motion of the piston 3 from the top dead center (TDC) to the bottom dead center (BDC) the intake valve 7 is opened, and the detonable gas mixture is pumped into the cylinder 2 of the compressor 1 through the intake port 6 using the supply system 8.
