Finite elements analysis of a thermodynamic model of a lightning-like plasma channel

摘要

In this paper a lightning-like plasma channel is simulated to estimate the temperature increase caused by a 30kA, 10/350μs lightning current flowing through it. Additionally, the expanded channel dimensions interacting with the surrounding air are estimated assuming the lightning-like channel as a 10 mm in diameter and 2 km long vertical column, with a conductivity of 13.4 MS/m. The two-dimensional Finite Element simulation integrates electromagnetic-, turbulent flow- and heat transfer-models.
