The analytic solution of the problem is determined in the characteristic plane. It signifies that linear solution in this plane reveals non-linear behavior in the physical plane. Also, the condition of shock formation has been determined by analyzing the growth and deterioration of shocks using transport equations. It is observed that nature of the solution completely depends upon relaxing gas parameters and non-idealness. All computations are done using computational package MATHEMATICA. � 2022 The Physical Society of the Republic of China (Taiwan)Hyperbolic PDEsNon-ideal gasRelaxing gasShock waveArticlehttps://doi.org/10.1016/j.cjph.2022.07.002
