Impact of Open Cell Bi-Component Structures on Distribution of Temperature Fields

Abstract

This article is focused on analysis of impacts of cellular structure on even heat distribution and heat removal rate from surface of the bi-component experimental part with using cooling potential of liquid technical gases. Experimental part had bi-component core/shell structure and both components were made of the same metal material. The only difference between them was their structure. The shell component of experimental part had compact and consistent structure. The core either had the same structure as the shell layer or it was created using fractal patterns with microporous structure of open cell character. Porosity influence on temperature field distribution on the part surface was assessed in two levels distinguished by different sizes of fractal patterns.
