  • A modern approach to characterizing surface roughness

    March 08, 2023
    Emmanuel Hitimana, Engineer, Research Roughness can be understood as a surface texture or height variation with respect to a perfectly flat or smooth surface. Tube and heat exchanger users are keenly interested in surface roughness because it affects pressure drop and heat transfer, which then impacts the thermal performance and cost...
