The first set of the experimental results belongs to unsteady flow.
The change of the temperature pattern repeats itself for a period of
tp (around 15 s). Hence, the flow is unsteady periodic flow.
Experimental Results Set 2
The second set of the experimental results is steady flow
since the temperature remains constant at around 27 oC. The
temperature value is independent of time.
Experimental Results Set 3
The third set of the experimental results is unsteady and
random. The value of the temperature varies in an unpredicted manner for
the whole period of 60 s.
