Deposition of Various Shapes Particles on a Rough Surface in Turbulent Flow
An experiment set-up is used to study wall deposition rate of particles on a rough surface in a turbulent channel flow. Deposition velocities for three classes of particles, namely, spherical glass particles, irregular shape polymer particles, and fibrous silicon particles are studied. The particle concentration at the test section was measured with the aid of an isokinetic probe in conjunction...

15 صفحه اولBoundary Layers and Heat Transfer on a Rotating Rough Disk
The study of flow and heat transfer over rotating circular disks is of great practical importance in understanding the cooling of rotatory machinery such as turbines, electric motors and design and manufacturing of computer disk drives. This paper presents an analysis of the flow and heat transfer over a heated infinite permeable rough disk. Boundary-layer approximation reduces the elliptic Nav...
متن کاملHomogenization of the Equations Governing the Flow Between a Slider and a Rough Spinning Disk
The main challenge in the design of hard-disk drives is to increase the density of data storage. Traditional disk-drive designs involve a read/write head positioned on a slider bearing that flies over a smooth spinning magnetic disk. The demand for larger data storage has made it necessary to reduce the minimum gap height for various design features of the air-bearing surface to be in the range...
متن کاملSpinning rough disk moving in a rarefied medium
A spinning rough disk moves through a rarefied medium on the plane. The roughness is formed by small cavities on the disk boundary. The medium is so rare that mutual interaction of particles can be neglected. All collisions of particles with the disk are perfectly elastic; there may happen multiple collisions in the cavities. We calculate the force of resistance acting on the body and examine h...
