Symmetry analysis and conservation laws for description of waves in bubbly liquid

This study deals with symmetry group properties and conservation laws of an extended Kudryashov-Sinelshchikov (K-S) equation in the bubbly liquid. We study Lie symmetries, symmetry reductions and exact solutions of the non-linear wave equation. By applying a direct method the local conservation laws associated to the (K-S) equation are also obtained.
