Research Project
Gather Experimental data for two-phase flow of a jet ejector pump
Two phase flow is difficult to characterize
Use experimental data

Day 1: Lesson Plan
August, 2011 Pretest Also ask Students to bring 100 pictures
October, 2011 Present my E3 research using Poster and
Powerpoint Discuss two-phase flow Demonstrate two phase flow: Use a coke

Day 2: Pixel Face
Take a picture of their own face
UploadMagnifyCount how many pixels wide and long in their face

Two Phase Flow
Give students pictures of two phase flow; each group gets a different picture
Use Transparency overlay of graph paper to represent pixels
Mark gas as white and liquid as black Students count and calculate
fractions of liquid and gas and do a mass balance for the jet

Day 3: Picture Mosaic
Download free Andrea Mosaic software
Create a mosaic from their own pictures
![Page 12: Pump Jet Ejector](https://reader036.vdocuments.us/reader036/viewer/2022062422/5681332b550346895d9a2042/html5/thumbnails/12.jpg)
First choose a picture for the base

Set Mosaic Parameters
Mosaic size and resolution Tile size and duplication Pattern Color change Tile variants Etc.

Create Mosaic
Ooops! Pixels are too big.Change parameters and try again!

Smaller Pixels are a Tradeoff

Pre/Post Test
When sampling an image spatially, the sampling rate might have units of ____________. pixels/cm Answer pixels/sec cm/pixel pixels
![Page 18: Pump Jet Ejector](https://reader036.vdocuments.us/reader036/viewer/2022062422/5681332b550346895d9a2042/html5/thumbnails/18.jpg)
Spatial quantization refers to the process by which we assign the number of pixels in an image.
Answer the frame rate of a movie. the shape of the pixels in an image. the numbers assigned to each pixel.

A picture that has many small details would need to be sampled with a large pixel size. a high spatial sampling rate. Answer a high bit quantization level. a low bit quantization level.
