What is the heat transfer coefficient of oil?

In summary, the person is asking for the heat transfer coefficient of oil, specifically polyolester. They also provide some helpful links for more information. The conversation ends with a mention of the TV series and a warning to watch out for a character named Gargamel.

Hi,

Does anyone know the heat transfer coefficient (&lambda in W K^-1 m^-1) of oil. I'm looking for this for polyolester, but if you have data of another oil, tha't would be fine!

Thanks,

Smurfje

1. What is heat transfer coefficient?

Heat transfer coefficient is a measure of how easily heat can transfer through a material. It is defined as the amount of heat transferred per unit area per unit time for a temperature difference of one degree.

2. How is heat transfer coefficient measured?

Heat transfer coefficient is typically measured using experimental methods, such as heat flux sensors or temperature sensors, to determine the rate of heat transfer through a material. It can also be calculated using mathematical models and equations.

3. What factors affect heat transfer coefficient?

The heat transfer coefficient of a material can be affected by several factors, including the material's thermal conductivity, surface roughness, and temperature difference between the two surfaces. Other factors may include the presence of a fluid or gas, as well as the material's thickness and composition.

4. How does heat transfer coefficient impact energy efficiency?

A higher heat transfer coefficient means that heat can transfer more easily through a material, making it less energy efficient. Lower heat transfer coefficients are desirable for materials used in insulation or energy-saving applications.

5. What are some common applications of heat transfer coefficient?

Heat transfer coefficient is an important concept in many industries, including building and construction, aerospace, and automotive. It is used to design and optimize materials for applications such as insulation, heat exchangers, and cooling systems.
