Flow Controller Linearization & Calibration Challenges Spring 2009

Subteam Leader:Unknown

Number of team members needed: 1-3

Important team member skills:

• Knowledge of data aquisition software
• Medium level understanding of fluid mechanics

Challenges

• Verify the possibility of internal deformation causing head loss within the tube
• different tubing diameters- how is the flow affected by different tube sizes? and is there still divergence from the equations in large diameter tubing?
• Non-negligible losses- Minor losses with major effects may be accumulating in the tube due to constant bending and are causing an accumulated substantial head loss. Due to internal deformation, should major losses be considered?
• Early transition to turbulent flow- induce turbulent flow to better understand the upper bound of the design technology
  • Is the flow control device feasible in the turbulent range?
  • Is there any benefit to pushing the technology to higher and higher laminar flow rates?
  • What is the viability of a dual dosing system or using a dosing tube which expands to control flow?
