Abstract

This study explores the effects of pipe wall properties (thermal conductivity k and wall thickness t w ) on the heat transfer performance of a rectangular thermosyphon with a phase change material (PCM) suspension and a geometric configuration (aspect ratio = 1; dimensionless heating section length = 0.8; dimensionless relative elevation between the cooling and the heating sections = 2) that ensures the optimum heat transfer efficiency in the cooling section. The following parameter ranges are studied: the dimensionless loop wall thickness (0 to 0.5), wall-to-fluid thermal conductivity ratio (0.1 to 100), modified Rayleigh number (10 10 to 10 11 ), and volumetric fraction of PCM particles (0 to 10%). The results show that appropriate selection of k and t w can lead to improved heat transfer effectiveness in the cooling section of the PCM suspension-containing rectangular thermosyphon.
