dc.description.abstract | In search of a more accurate method of measuring heat flux,
a new approach to
the solution of the inverse heat conduction problem is examined. The inverse
heat conduction problem traditionally uses temperature measurements to
estimate boundary heat fluxes. Inverse problems are ill-posed, so small
errors inherent in the
temperature measurement are amplified in the solution. Research shows that
solutions for heat flux are more accurate with less error using heating rate
measurements rather than using temperature measurements. Because there
currently is no method of measuring heating rate, defined as the first time
derivative of temperature, the author proposes a
new method of heating rate determination using thermographic phosphors.
Thermographic phosphors are traditionally used
in non-contact thermometry applications under steady state conditions. The
aim of this thesis is to show that thermographic phosphors may be used to
measure both temperature and heating rate under transient thermal conditions.
Experimental results show that with a significant reduction of noise in the
data, this method has the potential for measuring heating
rate. | |
