“…Mat vd. [9] üç borulu tüplü (iç içe geçmiş üç tüp) ısı değiştiricisinde RT82 FDM kullanarak erime süresini ticari bir HAD yazılımı olan Fluent programında iki boyutlu nümerik modelde incelemişlerdir. Erime sürecinde ısı transferini üç borulu tüplü ısı değiştiricisinde içten kanatçıklı, dıştan kanatçıklı ve hem içten hem de dıştan kanatçıklı olarak üç modelde inceleyerek FDM erime oranlarında önemli bir fark olmadığını ve erime zamanının içten ve dıştan kanatçıklı üç borulu tüplü ısı değiştiricisi kullanarak erime süresinin % 43 azaltılabileceğini göstermişlerdir.…”

A physical model to investigate the melting process around a multiple of heating cylinders in the presence of the natural convection has been carried out. A numerical code is developed using an unstructured finite-volume method and an enthalpy porosity technique to solve for natural convection coupled to solid-liquid phase change. It is found that during the melting process around the cylinders, natural convection circulation around each cylinder interacts with the other cylinders to influence the melt shape. In addition to natural convection, the heat source arrangement is an important factor in determining the melt shape.

Impact of nanofluid natural convection due to magnetic field in existence of melting heat transfer is simulated using CVFEM in this research. KKL model is taken into account to obtain properties of CuO-H 2 O nanofluid. Roles of melting parameter ( ), CuO-H 2 O volume fraction ( ), Hartmann number (Ha), and Rayleigh (Ra) number are depicted in outputs. Results depict that temperature gradient improves with rise of Rayleigh number and melting parameter. Nusselt number detracts with rise of Ha. At the end, a comparison as a limiting case of the considered problem with the existing studies is made and found in good agreement.
