Finds documents with one or the other search term (e.g. porsche OR volkswagen).
Finds documents with all search terms. Blank space is understood as AND (e.g. man robot production).
Finds documents with no appearance of the word behind NOT (e.g. ford NOT "harrison ford").
Finds documents where the search term is mentioned at least "n" times."n" may be any number (e.g. COUNT(gear)>8).
Finds documents with both search terms in any word order, permitting "n" words as a maximum distance between them. Best choose between 15 and 30 (e.g. NEAR(recruit, professionals, 20)).
Finds documents with the search term in word versions or composites. The asterisk * marks whether you wish them BEFORE, BEHIND, or BEFORE and BEHIND the search term (e.g. lightweight*, *lightweight, *lightweight*).
Finds documents with the search term in different spellings. "?" allows only one character (e.g. organi?ation).
Special characters are understood as AND (e.g. Miller Bros. & Sons).

Abstract

This chapter delves into the experimental study of melting and solidification processes within a Trombe wall integrated with multi-row channel phase change material (MCPCM) wallboards. The research focuses on the phase change patterns of paraffin wax, temperature distributions inside the PCM wall, and the impact of copper tubes on heat transfer. The study reveals that the MCPCM-TW model demonstrates a 10.7% increase in melting efficiency and a 13.19% increase in discharging rate compared to traditional PCM-TW. The experiments were conducted under varying heat fluxes, and the results highlight the enhanced performance of the MCPCM-TW in both melting and solidification processes. The integration of copper tubes significantly accelerates the melting rate by increasing the heat exchange area and promoting convection. The study also provides a qualitative assessment of the factors contributing to the observed acceleration in melting. The findings offer valuable insights for the design and optimization of PCM walls, aiming to improve solar energy utilization and indoor thermal comfort in buildings.
