Project 2:

Computing NO and O2 fluorescence spectra with vibrational nonequilibrium

Correct measurement of temperature using laser-induced fluorescence

spectra requires precise modelling of the molecules' behaviour,

accounting for contributions from all the important molecular species.  A

model for computing spectra has been produced, but does not account

for the possibility of freezing of the molecules' vibrational energy.

This is a common phenomenon for shock tube nozzle flows, where

vibrationally excited oxygen fluorescence may interfere with the

measured fluorescence from nitric oxide.  The project would involve

writing a code that models the spectra of vibrationally excited nitric oxide

and oxygen, comparing the predicted signal interference

with previously determined experimental measurements.

Skills developed

Computer modelling of fluorescence spectra

Skills required

Basic knowledge of spectroscopy or a demonstrated ability to learn

physical and mathematical concepts quickly.
