  • In recent years, non-linear fractional differential equations (NFDEs) have been attracted much interest and it has gained popularity among the researchers

  • It is remarkable to see that the traveling wave solution w1, w2, w3, w4, w5, w6, w7, w8, and w9 of the space-time fractional-coupled Burgers equations and space-time fractional foam drainage equation are fresh and further more general and have not been established in the previous solutions

  • We have obtained more new wave solutions by used the generalized (G′/G)-expansion method for these equations which have not been reported in the previous literature

Summary

Introduction

Non-linear fractional differential equations (NFDEs) have been attracted much interest and it has gained popularity among the researchers. D and k into Equation (3.4), we attain more general type and new exact traveling wave solutions of the non-linear fractional differential Equation (3.1). The coupled burgers equations In this sub-section, we determine some new close form traveling wave solutions to the space-time fractional-coupled Burgers equations by making use of the generalized (G′/G)-expansion method. The foam drainage equation we determine some appropriate close form traveling wave solutions to the spacetime fractional foam drainage equation by making use of the generalized (G′/G)-expansion method. The fractional foam drainage equation is a model of the flow of liquid through the channels and nodes between the bubbles, driven by gravity and capillarity This equation is described as the demandable model of waves on shallow water surface, ion acoustic waves in plasma, and the waves on foam maybe explain in terms of a non-linear PDE for the foam density as a function of time and vertical position.
