Ion‐Flow Field Modelling of ± 1100 kV Transmission Lines Under Strong‐Wind Scenarios Using the Multiple Relaxation Time Lattice Boltzmann Method

High Voltage, EarlyView.
ABSTRACT To solve the ion‐flow field of ultrahigh‐voltage direct current (UHVDC) transmission lines under strong‐wind scenarios, the multiple relaxation time lattice Boltzmann method (MRT‐LBM) is adopted. Compared with previous ion‐flow studies predominantly based on the single relaxation time LBM, the MRT‐LBM framework provides improved numerical ...
