Heat Transfer Calculation

In summary, the conversation discusses the desire to perform a first principles heat transfer calculation for an ideal, monoatomic gas at entry temperature T, and pressure P flowing at a small velocity v through a stainless steel tube at a uniform temperature T' > T. However, the speaker expresses difficulty in finding such a calculation without relying on literature values of the heat transfer coefficient, and is willing to settle for an ab-initio calculation at v=0 due to the complexity of the factors involved.

I would like to do a first principles heat transfer calculation for an ideal, monoatomic gas at entry temperature T, and pressure P flowing at velocity v (v is small, so flow is laminar) through a stainless steel tube at some uniform temperature T' > T.

But if someone has done this calculation before, and I find it hard to believe that no one has, I'd rather just copy off them. :redface:

After some moderate searching through Mass & Heat Transfer books, I haven't found anything that doesn't use some literature value of the heat transfer coefficient, h. Where can I find a more fundamental calculation than that ? I will settle for an ab-initio calculation at v=0.

There are too many factors to make calculation of the heat transfer coefficient practical. We all resort to empirical numbers for such cases.
 

Related to Heat Transfer Calculation

1. What is heat transfer calculation?

Heat transfer calculation is a process of determining the amount of heat that is transferred between two or more objects. It involves understanding the principles of thermodynamics and using mathematical equations to calculate the rate of heat transfer.

2. Why is heat transfer calculation important?

Heat transfer calculation is important in various fields of science and engineering, as it helps in designing and optimizing systems that involve heat transfer, such as power plants, refrigeration systems, and even cooking appliances. It also helps in understanding and predicting the behavior of materials and substances when exposed to different temperatures.

3. What are the different types of heat transfer?

The three main types of heat transfer are conduction, convection, and radiation. Conduction is the transfer of heat through a solid medium, convection is the transfer of heat through fluids, and radiation is the transfer of heat through electromagnetic waves.

4. How is heat transfer calculation performed?

Heat transfer calculation involves using mathematical equations, such as Fourier's law of heat conduction, Newton's law of cooling, and the Stefan-Boltzmann law, to determine the rate of heat transfer between two objects. These equations take into account factors such as temperature difference, surface area, and material properties.

5. What are some applications of heat transfer calculation?

Heat transfer calculation has various applications, including designing and optimizing thermal insulation, predicting the performance of heat exchangers, determining the heat loss in buildings, and understanding the behavior of materials during heating and cooling processes. It is also used in fields such as meteorology, geology, and biophysics, to study the movement of heat in the atmosphere, earth, and living organisms, respectively.
