The Development And Validation Of An Isokinetic Calibration System For Multiple Aerosol Instruments, Wendy Michelle Merkley
The Development And Validation Of An Isokinetic Calibration System For Multiple Aerosol Instruments, Wendy Michelle Merkley
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
A multi-port calibration xture for the cross calibration of aerosol point sensors has been developed. The system was designed for comparative calibrations of instruments using differing measurement methods such as optical particle counters, aerodynamic impactors, etc. Four isokinetic sampling ports are attached to a laminar ow plenum such that all four sampling ports sample identical aerosol concentrations under identical ow conditions. Correlation and correction factors are applied to each instrument creating a standard method. This standard method can be applied to inter-compare and calibrate aerosol sensing instrumentation and/or to characterize the microphysical properties of a test aerosol. The performance of …

Interpolation And Validation Of Arced Labyrinth Weir Discharge Coefficients, Rhen Daniel Thurgood
All Graduate Plan B and other Reports, Spring 1920 to Spring 2023
Arced labyrinth weirs have been researched in recent years as a viable option to help increase spillway discharge capacity. Previously published data have indicated the hydraulic efficiency of these weirs with several configurations at different sidewall angles (α=6°, α=12°, and α=20°), expressed in terms of the discharge coefficients. These published discharge coefficient data were used in the current study, along with new experimental data, to develop a better understanding of the accuracy associated with interpolating arced labyrinth weir discharge coefficients. Discharge coefficient data for a 16° arced labyrinth weir (of similar physical size to the arced labyrinth weirs in the …
