Abstract

We present the results of numerical modeling of the interaction of a fraction of heavy charged particles, immersed in a gravitational field and an external uniform electric field, with a weakly conducting charged ascending convective flow within the framework of the approach proposed in (Davydenko et al. in Radiophys. Quantum Electron. 67:423–430, 2024). The features of the instability developing in the system and the characteristics of the emerging small-scale variations of the electric field depending on the parameters of heavy particles are studied. It is shown that the instability growth rate decreases with increasing radius of particles and decreasing absolute value of their charge.

多分散对流中的电扰动特性

在Davydenko et al.在Radiophys中提出的方法框架内，我们展示了沉浸在引力场和外部均匀电场中的一部分重带电粒子与弱导电带电上升对流相互作用的数值模拟结果。量子电子。67:423 - 430,2024)。研究了系统发展的不稳定性特征以及随着重粒子参数的变化而出现的电场小尺度变化特征。结果表明，不稳定性增长率随粒子半径的增大和电荷绝对值的减小而减小。
