The performance of partially hydrolyzed polyacrylamide (HPAM), which is the most commercially used polymer in drag reduction (DR) applications, is affected by several factors. These factors include ...

The economic load dispatch (ELD) problems considering nonlinear characteristics where an optimal combination of power generating units is selected in order to minimize the total cost by economic ...

In this work, we combined three-dimensional (3D) scaffolds with flow perfusion bioreactors to evaluate the gradient effects of scaffold architecture and mechanical stimulation, respectively, on tumor ...

Some of the effects that therapeutic ultrasound has in medicine and biology may be associated with steady oscillations of gas bubbles in liquid, very close to tissue surface. The bubble oscillations ...

The study of multiphase flows gained much importance because of its extensive applications in nature and industry. These flows possess two or more thermodynamic phases, for example, one component ...

There are two main types of fluid flow - laminar flow, in which the fluid flows smoothly in layers, and turbulent flow, which is characterised by chaotic motion and large amounts of mixing. In ...

In large and medium-sized mammalian arteries, shear stress appears to be closely regulated between 5 and 20 dyne/cm 2. 1 Large arteries respond to acute changes in flow and shear stress by changing ...

BACKGROUND: Mechanical cues exerted by shear stress from blood flow remodel an initial vascular plexus into a ramifying array of large and small vessels. Hemodynamic forces trigger changes in ...
