ACTIVE COOLING PERFORMANCE OF ALL-COMPOSITE LATTICE TRUSS CORE SANDWICH STRUCTURE
Краткое описание
A theoretical and numerical study of fluid flow and heat transfer characteristics of an all-composite lattice truss core sandwich structure with a constant localized internal heat source under forced water convection is presented. The local fluid characteristics and the mechanism of active cooling are explored by a velocity field analysis. Further, based on the temperature field analysis, the responses of the structural maximum temperature to flow velocity and heat flux are revealed. Three dimensionless parameters scaled by the structural channel height are used to characterize and assess the active cooling performance of the structure. In comparison with numerous heat dissipation media, the result shows that the ultralightweight all-composite lattice truss core sandwich structure has an excellent comprehensive active cooling performance.
