Relaxation function method for evaluation of general thermal loads

kasahara, Naoto

A rational analysis method for general thermal transient problems was proposed, by utilizing tansient response characteristics of structures. Structures can not respond to quick change of fluid temperature, since they have finite time constants. Low rate changes of fluid temperature hardly induce thermal stresses because of temperature homogenization in structures. In order to quantify above transient characteristics, author developed a relaxation function method that describes Green function of structures. This function can be applied to sensitivity analysis of thermal stress to fluid temperature and to optimization of heat removal systems.
