Enhanced Diffusion in Longitudinal Plasma Turbulence

9306221卡里该项目旨在解决等离子体湍流中的一些问题，这些问题集中在拟线性理论的有效性领域。最近的数值模拟表明，在线性范围内，缓慢增长的湍流谱的增长率可以得到提高。实验和早期的模拟没有表现出这种增强。将开展的数值工作旨在通过使用比目前可用的数值方法快一个数量级的简化方法进行数值模拟来最终回答这个问题。***

9306221 Cary The project is designed to settle some questions in plasma turbulence which center around the domain of validity of the quasilinear theory. Recent numerical simulations suggest that the growth rate of a slowly growing turbulent spectrum can be enhanced over the linear value. Experiments and early simulations do not exhibit this enhancement. The numerical work to be undertaken is designed to definitively answer the question by performing numerical simulations using simplistic methods which are an order of magnitude faster than currently available numerical approaches. ***
