Limiting Current on a Rotating Disk with Radial Diffusion

Boundary 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...

Vibration Analysis of Rotating Shaft with Loose Disk

In this paper energy method is used to calculate rotor response with loose rotating disk on it. System equation of motion is obtained based on energy method and Lagrange equation. Mathematical modeling of loose disk in a rotor bearing system has resulted in terms similar to unbalance and gyroscopic effect in the system equation of motion. The effect of loose disk axial position and orthotropic ...

Measuring isotropic diffusion with rotating diffusion gradients

Introduction Measuring the mean apparent diffusion coefficient (ADC) provides valuable contrast in studying disease processes such as stroke and tumours. ADC is usually measured by acquiring a reference image and 3 images with diffusion weighting (DW) applied in 3 orthogonal directions. ADC is then defined as the mean of the 3 diffusivity maps. This can be time consuming, and single-shot method...

Diffusion boundary layer of a rotating disk electrode as a thin-layer spectroelectrochemical cell.

A UV-visible rapid scan spectrophotometer (RSS) was coupled to a Au rotating disk electrode (RDE) for monitoring at near-normal incidence the reflection-absorption spectrum of the diffusion boundary layer in [Fe(CN)(6)](4)(-) aqueous solutions over a potential region in which [Fe(CN)(6)](4-) oxidizes, generating highly absorbing [Fe(CN)(6)](3-) (lambda(max) = 420 nm). Measurements were performe...
