论文摘要
在本文中，我们开发了由空间不均匀的静电离子离子循环微扰动驱动的对流中尺度流的动力学理论，并在基座等离子体中具有剪切的poloidal poloidal流动。开发的动力学理论预测了剪切的多型对流流的产生，以及具有径向流速梯度的径向压缩流的产生。对流流的开发流体动力学理论揭示了径向压缩流动，这是陡峭的基座密度谱的形成的主要因素，并随时间呈指数增长。这种梯度密度的生长受到径向振荡的形成，随着底座等离子体到刮擦层的时间离子流出的形成。
In this paper, we develop the kinetic and hydrodynamic theories of the convective mesoscale flows driven by the spatially inhomogeneous electrostatic ion cyclotron parametric microturbulence in the pedestal plasma with a sheared poloidal flow. The developed kinetic theory predicts the generation of the sheared poloidal convective flow, and of the radial compressed flow with radial flow velocity gradient. The developed hydrodynamic theory of the convective flows reveals the radial compressed convective flow as the dominant factor in the formation of the steep pedestal density profile with density gradient exponentially growing with time. This gradient density growth is limited by the formation of the radial oscillating with time ion outflow of pedestal plasma to scrape-off layer.
