Compression of turbulent plasma can amplify the turbulent kinetic energy, if the compression is fast compared to the viscous dissipation time of the turbulent eddies. A sudden viscous dissipation mechanism is demonstrated, whereby this amplified turbulent kinetic energy is rapidly converted into thermal energy, suggesting a new paradigm for fast ignition inertial fusion.
如果压缩速度比湍流涡旋的粘性耗散时间快,湍流等离子体的压缩可以放大湍动能。本文展示了一种突然的粘性耗散机制,通过该机制,这种放大的湍动能迅速转化为热能,这为快点火惯性聚变提出了一种新范式。
