Hello, im trying to simulate a solar water collector, but im having problems heating the water in the fluid region. My model consist of 3 volumes. The top one is the air pocket where the sun rays comes throught and heats up the copper volume which heats up the fluid region.  \"\"In the simulation i use the rosseland solar model\"\"<\/p>\n

The fluid should heat up, but it doesnt, it aactually heats up just decimals, and ive tried everything. Ive applied a sharing topolgy type of mesh, where everything should be conected and not non-conformal.<\/p>\n

\"\"<\/p>\n

As you can see, the copper is pretty hot, almost 400 kelvin, but the water stays cold, the inlet water velocity is 0.02m\/s, and the tube diameter is like 5 cm.<\/p>\n

\"\"<\/p>\n

This is the outlet water temperature. Can someone help me solve this issue??<\/p>\n","protected":false},"template":"","class_list":["post-377872","topic","type-topic","status-publish","hentry","topic-tag-fluent-cfd-ansys-1","topic-tag-heatfluxfluentnaturalconvectionexternalflowansys-1","topic-tag-thermal-radiation-1","topic-tag-ansys-thermal-1","topic-tag-heat-convection-1","topic-tag-internal-flow-simulation","topic-tag-meshing","topic-tag-solar-calculator-1","topic-tag-solar-load","topic-tag-solar-radiation","topic-tag-solar-ray-tracing-2"],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
