Assume steady-state, one-dimensional heat conduction through the axisymmetric shape shown below.
Assuming constant properties and no internal heat generation, sketch the temperature distribution on
To sketch: The temperature distribution on T-x coordinates and explain the shape.
Explanation of Solution
Draw the axisymmetric shape as shown below:
Write the expression as per Fourier law.
Here,
Since the heat transfer through the body remains constant and thermal conductivity of the body remains constant, the Fourier law can be explained as:
The above expression indicated that temperature and thickness is inversely proportional to one another.
On T-x curve the independent variable is x and the dependent variable is T .
Draw the T-x curve for axisymmetric shape as shown below:
The T-xcurve for axisymmetric shape is shown above and the slope

- Note: Don’t use Heissler charts to answer this question Note2: You’re free to make assumptions regarding any value you think you need in order to solve the problem. Just explain your reasoning behind your assumption in a logical manner. Note3: please explain clearly and step by steparrow_forwardDo fast i will give you good ratearrow_forwardThe thermal conductivity of a specific material is highly dependent on a number of factors. These include the temperature gradient, the properties of the material, and the path length that the heat follows. My question is how to add thermal conductivity? for example SS316 material has thermal conductivity=15W/mk if Gyroid shape is created with SS316 then what will be the total thermal conductivity?arrow_forward
