Don’t just review the notes to answer these questions, literally write the answers down on paper, as if you were taking a quiz.
- When we have variable material properties for transport (like diffusivity, thermal conductivity, or viscosity), how is the face value computed?
- Why is this better than using a simple linear interpolation?
- T/F: while one method of evaluating material properties at faces is better than the other, both methods will be strictly conservative when used in Finite Volume methods.
- Schetch the temperature profile that would develop between two adjacent materials subject to conduction when the material on the right is an insulator.
- T/F: a linear temperature profile between two materials with different thermal conductivities implies a discontinuous heat flux.
- What is grid decoupling?
- Draw a picture to illustrate the problem in 1D and 2D.
- What is one method for overcoming grid decoupling problems?
