Experimental feed mixer performance study

FEED 1 ST MIXER ( typ SIS ) 1 ST IF 2 ND MIXER

Introduction This report describes the conceptual design of certain parts of the local oscillator subsystem of the ALMA telescope, namely those parts concerned with ne control of the phase of the LO signals, along with related considerations for the correlator and the real-time software. Precise control of the LO phase is needed for fringe tracking, which is simply a matter of causing the LO to...

The Experimental Study of Effective Parameters on Mean Drop Size in a Mixer-Settler

CASE STUDY: Feed Intake and Performance of Heifers Sired by High- or Low-Residual Feed Intake

The objective of this project was to investigate the effects of selecting sires for residual feed intake (RFI) on the performance of their daughters. Bulls with low or high estimated breeding values (EBV) for RFI were selected from the Angus Society of Australia sire summary and mated to Angus cross commercial cows at the Kansas State University Cow-Calf Unit in 2005 and 2006. The average EBV o...

An Experimental Study of Turbulent Mixing in a Tee Mixer Using PIV and PLIF

Turbulent scalar mixing in the near field of a tee mixer (transverse jet in a pipe) is studied using Particle Image Velocimetry (PIV) and Planar Laser Induced Fluorescence (PLIF). Two jet-to-pipe velocity ratios, r = 3.06 and r = 5.04, are investigated for a turbulent pipe flow at a Reynolds number of 20,850. The laser measurement techniques are described, typical flow structures in the near fi...

Numerical and experimental observation of chaotic mixing in microfluidic mixer

Both the chaotic mixers (Fig.1) adopt a two-layer overlapping channels structure, which is very efficient for fluid manipulations such as stretching and folding, splitting and recombination. Even at extremely low Re (~10), chaotic advection can be generated. Both particle tracing simulation (Fig. 2) and experimental results (Fig.3) show that as the fluids are driven through the mixer, striation...
