How does transient heat transfer from steady heat transfer? How does one-dimensional heat transfer differ from two-dimensional heat transfer?
The factor through which the transient heat transfer differs from a steady heat transfer.
The factor through which one-dimensional heat transfer differs from two-dimensional heat transfer.
Explanation of Solution
Heat transfer is classified as follows:
- Steady state heat transfer
- Transient state heat transfer
The steady state means a situation which is independent from time. Insteady state, the heat flux does not depend on time. Whereas, in transient heat transfer, the heat flux depends on the time. During the transient heat transfer the temperature of the medium varies with time and position both. The transient state heat transfer is also known as unsteady state heat transfer.
The heart transfer depends on the rate of heat transfer and direction. It classified as follows:
- One dimensional
- Two dimensional
- Three dimensional
In one-dimensional heat transfer the temperature variation takes place in only one direction and most of the heat transfer occurs in only one direction. While in case of two dimensional heat transfer the temperature variation takes place in two directions and the heat transfer flows in both directions.
