Heat performance and internal pressure loss are important reference standards in solar air heaters (SAH). In order to solve the problem of too large a pressure loss in SAH. an innovative SAH with sinusoidal baffles was proposed on the basis of folded baffle and semi-circular baffle air heaters. A computational fluid dynamics (CFD) simulation calculation was performed for the SAH with ... https://herbsdailyes.shop/product-category/cookies/
