This model explains the phase separation phenomenon. Understanding the prominent dynamic and static properties of this model and other models of this type is of great importance for the physical phenomena encountered in many areas of industry. Therefore, for such models, it is also important to obtain guiding solutions in obtaining new information. Many explicit wave solutions consisting of trigonometric, hyperbolic, rational, and exponential functions are found by using analytical techniques. The obtained solutions were verified with Maple by placing them back into the original equations. Moreover, graphical demonstrations for some of the obtained solutions are given.eninfo:eu-repo/semantics/closedAccessRiemann-hilbert approachDe-vries equationWaals normal-formOptical solitonsExtended (g '/g)-expansion methodItemSimplest equation methodVan der waals equationEngineeringMathematicsMechanicsPhysicsArticle00073823020000161763224210.1515/ijnsns-2021-00162191-0294
