A Numerical Technique for Analyzing Frequency Response of the Internal Temperature Field of a Solid Body Driven by Fluctuating Heat Transfer

摘要

An efficient numerical technique for predicting frequency response of the internal temperature field of a solid body, which is driven by fluctuating heat transfer between the surface of the body and a surrounding fluid, was developed to improve the thermal analysis relevant to various engineering applications. The proposed method is superior to conventional time-domain analysis methods, not only because it does not require cumbersome judgment whether the thermal field inside the solid body reaches a steady state or not but also because the frequency response can be obtained at the same time over the entire domain in the body.
