This model is regarded as a significant high-order nonlinear partial differential equation that incorporates additional spatial and dispersive effects to generalize the concepts to more complex wave dynamics, applicable in engineering and science to comprehend complex phenomena and systems. These models aid in predicting the kinematics and wave development of irregular wave trains. The properties of unidirectional wave spectra are considered as well in order to understand wave behavior and its effects in coastal areas. To investigate the solitary wave solutions in unidirectional wave model, we use advanced analytical methods such as the generalized projective Riccati equation method, the new improved generalized exponential–rational function method and Riccati modified extended simple equation method, as well as using mathematical simulations to get a better understanding of wave propagation. The use of nonlinear optical phenomena in fluid dynamics and a number of other research areas is greatly influenced by soliton theory research. This has led to a notable increase in the focus of scholars on the study of such solitons in the last several decades.

The recommended approaches result in a number of soliton solutions including dark, bright, bright dark, singular, periodic and combined solitons.

The obtain results reveal that the considered modified theory provides the viable solutions with a stable structure.</div></div>","PeriodicalId":49267,"journal":{"name":"High Energy Density Physics","volume":"57 ","pages":"Article 101239"},"PeriodicalIF":0.9,"publicationDate":"2025-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145568409","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"物理与天体物理","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
