Abstract

The modelling of shock waves in the interplanetary environment is a complex and a major problem  in solar physics. A hydrodynamical solution to the shock waves is proposed in this study. A discussion of the model and results of the papers published based on the model is the aim of this study. The model presents a solution that takes Reynolds number, adiabatic index, compression rate and the Mach number for upstream and downstream flow and derives an equality between them. A scale of the intensity of the shock waves is derived based on the model. The model’s usage with NASA’s ACE spacecraft has been published and the correlation of the shock parameters produced by model and the sunspot numbers have been correlated. Moreover, an artificial neural network based upon the said hydrodynamical model has also been designed to predict the shock parameters without the need of actual satellite data.
