EFFICIENCY AND PHASE REVIEW

BACKGROUND• Suction feeding in telost fish.

• Particle Image Velocimetry (PIV) used to visualize flow externally.

• Can Doppler Ultrasound (DUS) be used to visualize flow internally?

PROBLEM STATEMENT

• Currently: no understanding of flow inside mouth.

• Goal: design a test rig to utilize PIV & DUS to obtain full velocity profiles.

• Use PIV as control and compare DUS for internal flow data.

FEASIBILITY ANALYSIS

3D Fish Model:How long will it take to create a fish model and how will we test for functionality that resembles a real fish?

- Wait time for rapid prototyping machines: Unknown- Time to print all parts (using pre-existing CAD files): 3 Days- Time to assemble components: 5 Days- Time to create and assemble “Skin”: 7 Days- Time for complete integration of pump: 5 Days- Time for testing/adjustment of flow created: 10 Days (use iterative process of comparing flow data and adjusting pump settings)

Total Time for Creation: 30+ Days

3D Fish Model:How much cost will be involved in the creation of the 3D fish model?

- CAD files: $0- 3D printing cost: $0? (Possibly no cost to create components in the Brinkman Lab)- Latex sheet (12 in. x 12 in.): $8 (per sheet)- Electric pump: $25- Various tubing and accessories: $30

Total Cost: $63+

FEASIBILITY ANALYSIS CON’T

Test Rig Scaffolding Structure: How much will the test rig structure weight and how much will all the materials cost?

- Top of tank dimensions: 0.6 m x 0.6 m- Material to use: 6061 Aluminum- Approximate size/number of pieces: 0.05 m x 0.02 m x 0.6 m (4 pieces)- Density of 6061 Aluminum: 2700 kg/m^3

Total Weight of Scaffolding Structure: 6.4 kg

Total Cost of Raw Material: $55 (Price does not include manufacturing work to create fixturing)

Fish Feeder:How do we create a fish feeder that consistently delivers the right amount of food at the right time (and be compatible with a wide range of food sources)?

- Benchmark against “fish feeders” that are on the market today (Fish Mate F14).- Brainstorm ideas on how to adapt a product meant for dry food to accommodate live bait.- Perform extensive testing to validate subsystem concept.

FEASIBILITY ANALYSIS CON’T

Data Collection:How much data will be generated during test operation?

- Hz for PIV Camera (640 x 480 Resolution): 500- Hz for DUS Probe: 120 (24 kb/sec)- Seconds captured: 6- Number of pixels per frame: 307200- Number of bits per pixel: 32- Number of bytes per bit: 8

Total Data Quantity: 4 GB/test

Doppler Ultrasound:How far from the target can we place the probe to still achieve a high enough frame rate?

- Speed of sound in water: 1497 m/sec- Line Density per frame: ~64- Desired frame rate: 500 frames/sec

Maximum Distance From Target: 2.3 cm

PHASE REVIEW AND EFFICIENCYReasons for Inefficiency:

• Didn’t understand scope

• Inefficient methods

• Task not delegated to enough people

Ways we Improved:

• Created new methods (ex PUGH)

• Split up tasks and asked for help

Ways to be More Efficient in the Future:

• Be honest about how large a task is

• Be realistic about time to complete

• Always update progress on time
