title = "Assessment of the wear effects of low-speed jet impingement of alumina nanofluids on heat-exchanger materials",
abstract = "Nanofluids are nano-size-powder suspensions studied as enhanced alternatives to ordinary cooling fluids. But the wear and erosion effects from their interactions with heat-exchanger materials are largely unknown. The authors' research on evaluation methodologies for such surface-change phenomena includes the development of novel test rigs and assessment of surface analysis tools. Experimental research is discussed on typical nanofluids (2%-volume alumina-nanopowder in 50/50 ethylene glycol and water) which are jet-impinged on aluminium and copper during long tests with jet speeds of 3.5 m/s. The obtained substantially different surface modifications when same tests are conducted on aluminium and copper, and when comparing effects of the base fluids to those of its alumina-nanofluids, were assessed by roughness measurements, by weighing of removed-material, and by optical-microscopy. The likely mechanisms of accelerated erosion and abrasion, and the possibility of extrapolating the test-rig results and methodology to typical cooling materials are discussed.",
