...Asghar Noormohammadi; Bing-Chen Wang Purpose This paper aims to study turbulent dispersion of a passive plume emitting from a single elevated line source of different elevations in a plane channel flow by using direct numerical simulation (DNS). Design/methodology/approach The investigation...

...Abdul-Majid Wazwaz Purpose The purpose of this paper is concerned with developing two-mode higher-order modified Korteweg-de Vries (KdV) equations. The study shows that multiple soliton solutions exist for essential conditions related to the nonlinearity and dispersion parameters. Design...

... which advection or diffusion or reaction is more important. Some errors such as L₁ error, dispersion, dissipation errors and relative errors are tabulated. Moreover, the author compares some spectral properties of the method under different regimes. The author obtains the variation...

...Raafat G. Saadé; Semaan Sarraf In Northern Regions, ice covers that form on rivers, streams, and lakes with the onset of winter, cause various problems related to winter navigation and pollution dispersion among others. Warm water, from industrial plants,discharged into these rivers cause partial...
