Existing pattern
This pattern is created by applying the hit to the heating plates. By the changing temperature, the gas density on top of the plate changes shape. This pattern is found by two dimensional observing (in this case we are using a technique called ‘Schlieren Imaging’), which helps us to understand the relationship between heat convection phenomena and the changing of air density which occurs as a result. We see that there are more irregular lines and circular structures as the temperature is increased.
New Pattern
We can come up with a new pattern by looking at the density of the air at a single location. Plot this pattern by a graph which shows the relationship between the air density and time. This plot will result at a lower temperature (below)
We can compare this with a case where the temperature is higher and the frequency of the fluctuations in the air density is increased.
These two new patterns help us to guess the air density in any certain point in temperature without real temperature measurements. Also we can form new patterns by extending 2 dimensional patterns to 3 dimensional patterns like below.
Observing this new 3D pattern can help us think about the structure of air density and the relations between the circles and lines as the temperature changes.
