Heat transfer from flame in pipe

However, there are resources available for non steady-state heat transfer problems. These can be found in textbooks or online, and can provide a good starting point for understanding this type of problem. In summary, if you are not familiar with non steady-state heat transfer problems, there are resources available that can help you get started. These resources can be found in textbooks or online, and can provide a good foundation for understanding the complexities of this type of problem.

I am not familiar with non steady-state heat transfer problems, any resources on where I could get started would be a huge help:

There is a pipe filled with a fuel/air mixture. This mixture is ignited at one end of the pipe, so that the flame front propagates through the pipe. How can we determine the heat transfer through a portion of the pipe? Any equations or pointers would be greatly appreciated.

This is usually covered in a heat transfer course. It takes more than a few formulas to give a decent treatment of the subject.

I've taken one course, but we never went over a moving flame front, just general transient heat transfer problems. Does this not add more complexity to the problem?

Undoubtedly it does, due to the transient nature of the flame propagation.
 

1. What is heat transfer and how does it occur?

Heat transfer is the movement of thermal energy from one object to another due to a temperature difference. In the case of a flame in a pipe, heat transfer occurs through convection, where the hot gases from the flame rise and transfer heat to the walls of the pipe.

2. What factors affect the rate of heat transfer from a flame in a pipe?

The rate of heat transfer from a flame in a pipe is affected by several factors, including the temperature difference between the flame and the pipe, the surface area of the pipe, the type and thickness of the pipe material, and the velocity of the gases in the pipe.

3. How does the type of fuel used in the flame affect heat transfer in a pipe?

The type of fuel used in the flame can greatly affect heat transfer in a pipe. For example, a flame fueled by natural gas will have a higher temperature and therefore transfer more heat compared to a flame fueled by propane. This is because different fuels have different energy densities and burn at different temperatures.

4. Can the design of the pipe affect heat transfer from a flame?

Yes, the design of the pipe can affect heat transfer from a flame. A pipe with a larger diameter will have a larger surface area for heat transfer compared to a pipe with a smaller diameter. Additionally, the material and thickness of the pipe can also impact heat transfer.

5. How can heat transfer from a flame in a pipe be optimized?

To optimize heat transfer from a flame in a pipe, the temperature difference between the flame and the pipe should be maximized, and the surface area of the pipe should be increased. This can be achieved through proper insulation and using a pipe with a larger diameter. Additionally, controlling the velocity of the gases in the pipe can also help improve heat transfer efficiency.
