The fully developed laminar flow in helical elliptical pipes is influenced by curvature, torsion and aspect ratio of cross-section. With the aid of the symbolic manipulation technique, the governing equations were sol...
The effects of rotation and intermittent frequency on the flow transition ofsecondary flow and, main flow were examined in detail. Certain hitherto unknown flow patterns werefound. A numerical study was performed to s...
Transient laminar flows and pressure-wave propagation in pipes, commonly called as water hammer, have been analyzed. A pressure-wave equation and a linearized velocity equation were derived from the equations of mass ...
In this paper, a method for calculating the resistance force of high concentration non-homogeneous pipe flow was presented. The experiments were conducted in the bedstead of a recirculating pipeline. The measurement s...
In this paper, the dispersion of a soluble matter in couple stress fluids flowing through pipes and channels is investigated by taking into account the effects of homogeneous chemical reaction. The analytical expressi...
