http://thermalfluidscentral.org/e-resources/download.php?id=48 WebResults show that as Ram increases, both Nusselt and Sherwood numbers increase, indicating enhancement of heat and mass transfer across the cavity. Further, when the Lewis number is increased keeping the same thermal properties, reduction of mass diffusivity further enhances flow recirculation for aiding flows (N=1) within the cavity, …

Web13 nov. 2024 · This article discusses the possibility of further reducing the mass of the heat exchanger with stainless steel star-shaped fins while achieving good heat transfer performance. For this purpose, we perforated the fins with holes Ø2, Ø3, and Ø4 mm. Applying computational fluid dynamics (CFD) numerical analysis, we determined the … Webbased on the linear interpolation of the Nusselt number between Re = 2300 and Re = 10000 taking into account the finite length of the tube. In this way, conti-nuity of the Nusselt number was assured in the range from Re = 0 to Re = 1·10 7.
