Project Description
Project Background:
The use of nanoporous membranes is ideal for medicinal uses, in which extremely low flow is a necessity. One such case is to use these example membranes to control the injection of cells and other microscopic test specimens. Currently however, there are no definitive ways to measure flow characteristics across nanoporous membranes accurately.
Problem Statement:
The objective of this project is to characterize the flow rates through nanoporous membranes using different parameters for the flow. This will be achieved by using different gauges that output data onto a computer program showing the values for the flow rate, pressure and temperature rates of the fluid. This way, the characteristics of different variations of membranes can be analyzed for future use. Since flow going through the membrane is small, flow is expected to be non-Newtonian and not conform to common calculations.
Objectives/Scope:
1. Quantify expected flow across membrane through calculations and assumptions
2. Reduce the cost of measurement devices and system parts
3. Ability to physically observe the flow outside the system as well as under a microscope
4. Collect and store all data from within the system itself
5. Ability to change the flow rate of the system as well as control the sampling rate of data collection
Deliverables:
• Bill of materials
• CAD drawings
• Electrical Layout
• Updated Risk Assessment
• MSD2 Gantt Chart
Expected Project Benefits:
• Provide data that successfully characterizes flow across membranes.
• Ability to change flow rate through the system
• Keeping computerized records of all calculated and measured values obtained from the system
Core Team Members:
• Justin Davis
• Dave West
• Dave Sharp
Strategy & Approach
Assumptions & Constraints:
1. System must be able to withstand high pressure flow rates
2. Output data can be analyzed and edited for further calculations
3. Cost must be within a certain budget limit while still meeting customer criteria and specifications
