Description Convective heat transfer enhancement is critical in several industrial applications (e.g. electronic cooling). In our activity we:
- Design micro-structured patterned surfaces manufactured by both innovative and traditional techniques (Direct Metal Laser Sintering, laser etching, milling);
- Test them in air wind tunnel, where local average convective heat transfer coefficient is measured by an home made purposely developed sensor;
- Study the fluid dynamic interaction between surface and air boundary layer;
- Develop predictive models based on theory of turbulent flow, for estimating the heat transfer performances and optimize the surface features.
