This editorial provides an overview of a special issue dedicated to the 8th International Conference on Heat Transfer, Fluid Mechanics and ThermodynamicsHEFAT2011hosted in Mauritius. All papers for this conference were peer-reviewed and almost 150 papers were accepted. Of these, nine were selected for this issue and peer-reviewed for a second time according to journal standards. The nine articles focus on recent developments regarding heat transfer in industry and include condensation, frost formation, and frost melt-water retention on microgrooved brass surfaces under natural convection; large eddy simulation technique for the modeling of premixed and non-premixed combustion; nanoparticle-related heat transfer phenomena and their application in biomedical fields; heat rejection in condensers close to the critical point; industrial heat utilization through water management; influence of the geometry of open-cell aluminum foam on the thermohydraulic behavior in channel flow; effect of mesh grids on the turbulent mixing layer of an axisymmetric jet; use of the LIVE program at the Karlsruhe Institute of Technology to investigate core melt phenomena; and fluid flow characteristics and associated forced convection in curved ducts. The current issue of Heat Transfer Engineering is the eighth special journal issue dedicated to selected papers from the HEFAT conferences.
