| Abstract |
In heat exchange applications, the heat transfer efficiency could be improved by surface modifica-tions. Shot peening was one of the cost-effective methods to provide different surface roughness. The objectives of this study were: (1) to investigate the influences of the surface roughness on the heat transfer performance, and (2) to understand how the shot peening process parameters affect the sur-face roughness. The considered specimens were 316L stainless steel hollow tubes having smooth and rough surfaces. The computational fluid dynamics (CFD) simulation was used to observe the surface roughness effects. The CFD results showed that the convective heat transfer coefficients had linear relationships with the peak surface roughness (Rz). The finite element (FE) simulation was used to determine the effects of the shot peening process parameters. The FE results showed that the surface roughness was increased at higher sandblasting speeds and sand diameters. |
