the aim of this work is to describe the qualitative behavior of the solution set of a givensystem of fractional differential equations and limiting behavior of the dynamical system or flow defined by the system of fractional differential equations. in order to achieve this goal, it is first necessary to develop the local theory for fractional nonlinear systems. this is done by the extension of ...

when flow passes over the tube bundles, energy of flow transfers to the tubes. the fluid induced vibrations (fiv) imposed on the tubes is one of the important problems in analyzing the tube bundles and causes several problems. in this work, first, laminar flow around circular cylinder asymmetrically in a channel is simulated. the reynolds number is 20 and 100. the lift forces to tube are not ze...

in order to determine hydrological behavior and water management of sepidroud river (north of iran-guilan) the present study has focused on stream flow prediction by using artificial neural network. ten years observed inflow data (2000-2009) of sepidroud river were selected; then these data have been forecasted by using neural network. finally, predicted results are compared to the observed dat...

This article is proposed to address the melting heat transfer of a Jeffrey fluid in Blasius and Sakiadis flow caused due to a moving surface. Thermal radiation and a constant free stream are considered in this mathematical model. The non-linear coupled dimensionless equations from the governing equations are attained by employing appropriate similarity transformations. The resulting dimensionle...

The flow of fluid past a cylinder has been widely studied both analytically and numerically, and provides insight to the behavior of flow given different fluid properties. Particularly interesting is the transition from steady flow to vortex shedding in the wake of the cylinder. This behavior is dependent on several parameters, but most importantly, the Reynolds number (Re), which is a dimensio...

Understanding the behavior of reservoirs with flow regularization formed by hydroelectric power plants is essential for assessing water availability. The operationalization can be influenced both climatic characteristics and consequences resulting from human actions in basin. objective this study was to evaluate existing relationships between inflows outflows a reservoir, as well conventional s...
