Here you will evaluate heat dissipation from a hot, ribbed
surface. Your measurements will take place across one of the ribs shown
here as the dark block at the bottom of the interferogram.
In this particular experiment, an insulated rod has been placed across
the duct at the downstream end of each rib. This rod serves to impart
vertical momentum to the air flow to enhance heat transfer. Its effect
will not be considered in these problems.
Data from this experiment will consist of one frame (at left) from a
time-dependent interferogram recorded during the actual experiment.
View this recording
and note the unsteadiness of the interference fringes at
"steady state".
The objective is to take measurements from the interferogram and
deduce heat flow.
To carry out the experiment you must know the
data reduction strategy and the
parameters of the experimental setup.
