\ngeometry of the tube line system (harp and meander) is carried out. The collectors were tested to evaluate the
\ninfluence of the type of system on the thermal parameters due to the geometric differences. In both cases, tubes with
\na thickness of 2 mm and an outer diameter of 30 mm were used. The working medium in the systems was water with
\nan inlet temperature of 288K (15oC) and a velocity of 1m\/s. Numerical investigations were carried out on full-scale
\nsimulations using the Ansys Fluent software. The conducted simulations provided information on the dynamics of
\nchanges in the operating parameters of the installation. The analysis showed that the efficiency of the system can be
\nsignificantly improved by installing an appropriate absorber system. The results show that the greatest heating of the
\ncirculating medium occurs in the elbows and curves of the meander collector. After comparing the flows of the
\nworking medium through the meander and harp collectors, it was noticed that the meander collector is a more
\nefficient system than the harp collector.<\/p>\n","protected":false},"featured_media":0,"parent":0,"menu_order":0,"template":"","meta":[],"tags":[437,4901,482],"tematyka":[424],"class_list":["post-23895","artykul","type-artykul","status-publish","hentry","tag-computational-fluid-dynamics","tag-flat-plate-solar-collector","tag-thermal-efficiency","tematyka-sources-of-heat-and-electricity","has-post-title","has-post-date","has-post-category","has-post-tag","has-post-comment","has-post-author",""],"ptb_metabox":{"ptb_artykul_text_1":["PRZEMYS\u0141AW SZYMANEK"],"ptb_artykul_text_2":"10.36119\/15.2025.11.4","ptb_artykul_numer_miesi_cznika":"11\/2025 Instal pp.26-30","ptb_artykul_info_autor":"dr in\u017c.
