Thin Ceramic Coatings and Their Suitability Towards Scale Reduction in Heat Exchangers

Santos O., Nilsson M., Jensen A.H., Christiensen, A.B., Alfa Laval AB, SE

Scaling of heat exchangers in the chemical industry, district heating, power plants, etc results in a loss of performance which leads to production stops for cleaning and therefore increased operation costs. One approach to mitigate [...]

Thermal Performance of Silver/Water Nanofluids in Heat Exchangers

Bandarra Filho E.P., Oliveira G.A., Federal University of Uberlandia, BR

Nanofluids are fluid formed by dispersing solid particles of size ranging 1-100 nm (nanoparticles) in a given base fluid such as water or oil, for example. Regarding to the thermal potential, the researches on nanofluids [...]
