Surface finishing is often required for heat exchangers built using Additive Manufacturing to meet the desired pressure drop specifications. Moreover, the highly textured as-built surfaces result in a measured pressure drop higher than what is predicted by current correlations. The study focused on evaluating the pressure drop and friction factor variations depending on the type of surface and its conditions, with channels fabricated using laser powder directed energy deposition. After testing, the samples were destructively sectioned to obtain geometric and detailed surface texture information. This dataset corresponds to the raw data for the pressure drop testing and surface measurements that support the dissertation for Paul Gradl (Chapter 7, Directed Energy Deposition: an Additive Manufacturing Technology for Large High-Temperature Compact Heat Exchangers: Process characterization and fluid dynamic performance.)
