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