Zap Energy hits 37-million-degree electron temperatures in compact fusion device
Zap Energy announced April 23 that it has reached 1-3 keV plasma electron temperatures—roughly the equivalent of 11 to 37 million degrees Celsius—using its sheared-flow-stabilized Z-pinch approach to fusion. Reaching temperatures above that of the sun’s core (which is 10 million degrees Celsius temperature) is just one hurdle required before any fusion confinement concept can realistically pursue net gain and fusion energy.

Interaction between liquid metal flows and non-uniform magnetic fields occurs in certain regions of fusion power reactors such as the breeding blanket access pipes. Here, the resulting high MHD pressure drop leads to numerous design challenges. Therefore, in this paper we perform numerical simulations to analyze the effect of a non-uniform transverse magnetic field on a liquid metal flow in a straight electrically conducting pipe. In particular, we perform parametric analyses at different conductance ratios and magnetic interaction parameters to quantify their effect on MHD pressure drop in pipes. The results also help in establishing a range for the control parameters in which the flow transforms from a quasi-fully developed to a fully three-dimensional state.
