Convective Heat Transfer from a Heated Rotating Disk at Arbitrary Inclination Angle in Laminar Flow

In this paper, experimental data and numerical results of heat transfer from a heated rotating disk in still air are presented over a large range of inclination angles and a dimensionless correlation is developed for forced, natural and mixed convection. The measured Nusselt number over the rotating disk is compared with the numerical results. The goal of the present research is to develop a se...

Radiative Flow in a Luminous Disk

Radiatively-driven flow in a luminous disk is examined in the subrelativistic regime of (v/c), taking account of radiation transfer. The flow is assumed to be vertical, and the gravity and gas pressure are ignored. When internal heating is dropped, for a given optical depth and radiation pressure at the flow base (disk “inside”), where the flow speed is zero, the flow is analytically solved und...

Radiative Flow in a Luminous Disk II

Radiatively-driven transfer flow perpendicular to a luminous disk is examined in the subrelativistic regime of (v/c), taking into account the gravity of the central object. The flow is assumed to be vertical, and the gas pressure is ignored, while internal heating is assumed to be proportional to the gas density. The basic equations were numerically solved as a function of the optical depth, an...

Disk-aware Request Distribution-based Web Server Disk Power Management

This report presents studies, implementation, and simulation we conducted for the course project of COS518, Fall 2003. The course project was concerned with reducing power consumption by cluster-based web servers. We focused on server hard disks, a major source of server power consumption. We started with the modification of Logsim, a simulator for cluster-based web servers. The new simulator, ...
