Surface flow visualization using the thermal wakes of small heated spots.a surface flow visualization technique which uses the thermal wakes of an array of small heated spots to infer the local flow direction. The thermal wake is made visible using wide band thermochromic liquid crystals. The technique is illustrated using the endwall flow under a horseshoe vortex at the base of a right circular cylinder in a turbulent boundary layer. Comparisons to results generated using the oil of wintergreen technique were in good agreement. In addition to surface flow direction, the technique has the potential to be used to measure the heat transfer coefficient at each spot. Data are presented in terms of photographs of the actual visualization surface. The techniques is suitable for low speed flows.

What is the color of copper carbonate when heated?
When copper carbonate is heated, it changes from its green color to black copper oxide.
What color happen when lead nitrate heated?
When lead nitrate is heated, it decomposes to form lead oxide, nitrogen dioxide gas, and oxygen gas. The color produced will depend on the temperature and conditions of the reaction. In general, lead oxide is yellow to orange in color, while nitrogen dioxide is a reddish-brown gas.
What is the colour of brass when it is heated?
When brass is heated, it can oxidize and change color. It typically starts as a golden-yellow color when cool, then turns to a darker brown or red color as it gets heated, and eventually may develop blue or greenish hues due to oxidation.
What color does aluminium turn when heated?
When heated, aluminum typically turns a dull gray color due to the formation of an oxide layer on its surface. This oxide layer acts as a protective barrier to prevent further corrosion.
What colour is produced when sodium is heated?
When sodium is heated, it produces a bright yellow color due to the excitation of electrons in the sodium atoms. This yellow color is characteristic of the emission spectrum of sodium.
Does talc change color if heated?
Talc don't change the color if heated.
Does aluminum change color when heated?
Yes, aluminum does not change color when heated.
