Semester 1 Milestones and Deliverables

Three initial concept sketches based on researched designs

• Bandalong Litter Trap

• Clear Rivers Litter Trap

• Current Protoype deployed at Jacobson Park

This memo outlines design constraints and considerations decided with the team and reviewed by the Team Sponsor, Eric Dewalt.

Design calculations made by the team to find flowrate of a 100 year 24 hour storm event in Lexington, KY.

800 acre drainage area

11' by 9' elipical culvert

SCS CN Method

Revisions based on feedback from supervisors and sponsor

Double shear pin connections identified

Double shear force calculations based on various bolt diameter sizes

Drag force calculations on conservative estimate of backwall of the trash trap

Research of varying scaling methods typically used in open channel flow

Our model will be scaled down to be tested in the flume using dimensionless numbers.

• One method preserves dynamic forces

• The other method preserved kinematic forces

The team visited the Innovation Center to explore using 3D printers for our design.

The large model will be scaled down to be 3D printed to test in the flume.

Two different mini models were printed at the IC. 

• One model displays a standard dumpster

• The other model displays a dumpster with the front wall cut down for trash flow

The team adapted a CAD drawing of their final prototype.

In this deliverable, they attached the rendered drawing and made a few key callouts on the diagram.
