Web14 jan. 2014 · Abstract. Helicity is, like energy, a quadratic invariant of the Euler equations of ideal fluid flow, although, unlike energy, it is not sign definite. In physical terms, it represents the degree of linkage of the vortex lines of a flow, conserved when conditions are such that these vortex lines are frozen in the fluid. Web17 aug. 2024 · The Helicity Drive concept is a novel magneto-inertial fusion concept designed for a fusion space propulsion system. It has promising Lawson criterion performance scaling with input geometry resulting in power output that is uniquely scalable across thrust power classes (10s kW to GW levels) at high specific power.

Web7 mrt. 2024 · Measured fluctuation helicity is consistent with an α-dynamo electromotive force driving net current comparable to the macroscopic equilibrium current density. … The angular momentum J is the sum of an orbital angular momentum L and a spin S. The relationship between orbital angular momentum L, the position operator r and the linear momentum (orbit part) p is so L's component in the direction of p is zero. Thus, helicity is just the projection of the spin onto the direction of linear momentum. The helicity of a particle is positive (" right-handed") if the dire… trading combine options
