چکیده
|
In this paper the generalizations of the burgers-korteweg-de vries model with small parameter derived by kudryshov et al[ n.a. kudryashov, d.i. sinelshchikov. extended models of non-linear waves in liquid with gas bubbles, international journal of non-linear mechanics 63 (2014) 31-38] is studied. a comprehensive study on the approximate symmetry analysis of the waves models is presented. first, we obtain approximate symmetry for the equation. subsequently, in a physical application, using the first-order approximate symmetries, corresponding approximate invariant solutions to the perturbed non-linear models are obtained.
