Surface effects on deep flow

the effects of changing roughness on the flow structure in the bends

flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...

Effects of Mobile Phone Radiation on Surface Tension and Volume Flow Rate of Human Blood groups

Introduction: The great use of electrical appliances in different life applications is one of the most obvious concerns because of its possible health drawbacks. These investigation reports results of electromagnetic field effect emitted from mobile phones on some biophysical parameters of human blood belonging to blood groups A, B, AB & O collected from the normal persons. The parameters obser...

Surface Roughness Effects on Flow Boiling in Microchannels

On the Surface Diffusion Flow

In this paper we present recent existence, uniqueness, and stability results for the motion of immersed hypersurfaces driven by surface diffusion. We provide numerical simulations for curves and surfaces that exhibit the creation of singularities. Moreover, our numerical simulations show that the flow causes a loss of embeddedness for some initially embedded configurations.
