Mud Recycle is a process option for cane diffuser factories; it eliminates the need for a filter station by using the bed of shredded cane in the diffuser to separate out mud solids from the juice. This paper describes the Mud Recycle system at Maidstone mill and presents the results of a Mud Recycle trial that was carried out during the 1998 season. Maidstone switched to Mud Recycle on a perma...

The MODerate Resolution Imaging Spectroradiometer (MODIS) is one of the key instruments for the NASA s Earth Observing System (EOS). MODIS ProtoFlight Model (PFM) was launched on-board the EOS Terra spacecraft on December 18, 1999 and the MODIS Flight Model (FM-1) was launched on-board the EOS Aqua spacecraft on May 4, 2002. MODIS has 36 spectral bands with wavelengths ranging from 0.41 to 14.5...

Diffractive diffusers (phase gratings) are routinely used for homogenizing and beam shaping for laser beam applications. Another use for diffractive diffusers is in the reduction of speckle for pico-projection systems. While diffusers are unable to completely eliminate speckle they can be utilized to decrease the resultant contrast to provide a more visually acceptable image. Research has been ...

This study aimed to present the experimental results of two types turbines and attachments used in a hydro-compact generator. Two Horizontal Spiral Turbines (HSTs) with blade angles eighteen twenty-one degrees, respectively, three-blade turbine were tested experimented laboratory at five levels water flow rate ranging from 1–2 m/s. After efficiency torque values each identified, they installed ...

Turbulent flow, mainly originating from the rotor-stator interaction (RSI), is closely associated with normal and safe operation of centrifugal pump. In current research, to clarify turbulent flow in pump a vaned diffuser, non-intrusive LDA (Laser Doppler Anemometry) system applied measure velocity pulsation signals at different regions when operates various rates. Time frequency domain analysi...

One-dimensional stability analysis of a hydraulic system composed of a penstock, a runner, and a draft tube was carried out to determine the cause of the full load draft tube surge. It is assumed that the cavity volume at the runner exit is a function of the pressure at the vortex core evaluated from the instantaneous local pressure at the runner exit and an additional pressure decrease due to ...

The lag model proposed by Olsen and Coakley (2001) is applied to simulate the steady and unsteady transonic flows in a diffuser. The unsteady flows are induced by imposing fluctuating back-pressures. A fully implicit time–accurate multigrid algorithm is used for solving the Navier-Stokes equations and the coupled k-ω turbulence model equations. Two test cases are investigated, one with a weak s...

We report numerical and experimental studies on a droplet moving through an array of mirofluidic ratchets. Droplets are formed at a T junction and subsequently forced through microfluidic ratchets in the form of diffuser/nozzle structures. At the same flow rates of the continuous and the dispersed phases, the velocity of the droplet is determined by the viscosity of the continuous phase and the...
