Unsteady, one-dimensional flow over a plane-The rising hydrograph

Estimation of aquifer lower layer hydraulic conductivity values through base flow hydrograph rising limb analysis

[1] The estimation of catchment-averaged aquifer hydraulic conductivity values is usually performed through a base flow recession analysis. Relationships between the first time derivatives of the base flow and the base flow values themselves, derived for small and large values of time, are used for this purpose. However, in the derivation of the short-time equations, an initially fully saturate...

Three Dimensional Transonic Flow Computations Over a Projectile and at the Base Region

a semi analytical solution for rising limb of hydrograph in 2d overland flow

in almost all of the present mathematical models, the upstream subbasins, with overland flow as the dominant type of flow, are simulated as a rectangular plane. however, the converging plane is the closest shape to an actual upstream subbasin. the intricate nature of the governing equations of the overland flow on a converging plane is the cause of prolonged absence of an analytical or semi ana...

Unsteady three dimensional flow of couple stress fluid over a stretching surface with chemical reaction

Abstract. The unsteady three-dimensional flow of couple stress fluid over a stretched surface is investigated. Analysis has been performed in the presence of mass transfer and chemical reaction. Nonlinear flow analysis is computed by a homotopic approach. Plots are presented and analyzed for the various parameters of interest. A comparative study with existing solutions in a limiting sense is m...

Three Dimensional Laminar Convection Flow of Radiating Gas over a Backward Facing Step in a Duct

In this study, three-dimensional simulations are presented for laminar forced convection flow of a radiating gas over a backward-facing step in rectangular duct. The fluid is treated as a gray, absorbing, emitting and scattering medium. The three-dimensional Cartesian coordinate system is used to solve the governing equations which are conservations of mass, momentum and energy. These equations...
