6 FAQs about [Semi-infinite solid transient heat conduction energy storage]

What is transient heat conduction in semi-infinite solids?

Cases of transient heat conduction in semi-infinite solids with specified surface heat flux may be found in many fields of technology, as power engineering, internal combustion engines, civil engineering, etc. The source of heat flux can be, for example, exhaust gases, radiant burner, friction between solids, or flow of electric current.

What is transient conduction in a semi-in Nite solid?

For very short times, heat penetrates short distances under a surface, such that the dimension of the system is essentially in nitely large compared to the heat penetration. If the radius of curvature of the surface is much larger than the penetration, then the problem can be considered as transient conduction in a semi-in nite solid.

What is a semi-infinite solid?

A semi-infinite solid is an idealized body that has a single plane surface and extends to infinity in all directions except one. If a sudden change is imposed to this surface, transient one-dimensional conduction will occur within the solid. We can use the general heat equation, which has the following form :

What is unidirectional heat transfer in a semi-infinite body?

Varying temperature fields of the cylinder liners at combustion motors or reciprocal compressors are here farther examples. At periodic temperature variations penetrating a small depth, the problem can be considered as unidirectional heat transfer in the semi-infinite body with periodic variations of the boundary condition.

Which function describes a temperature distribution in a semi-infinite solid?

Function (33) describes a temperature distribution in the semi-infinite solid with an initial temperature \ ( {T_i} \), which surface is subjected to (for time \ ( t> 0 \)) a stepwise change in fluid temperature \ ( {T_ {\infty }}\ne {T_i} \).

Does a semi-infinite body have a heat generation exponentially decaying with position?
