The Journal of Thermal Science and Technology (JTST) is an Open Access, international peer-reviewed journal jointly edited and published by the Thermal Engineering Division of JSME and the Heat Transfer Society of Japan (HTSJ). The objective of JTST is to spread internationally knowledge generated through excellent research and state-of-the-art technology development in the field of thermal engineering. JTST takes over the fields of thermal engineering and heat transfer from the JSME International Journal, Series B that has been discontinued since January, 2007 and also the former Thermal Science and Engineering by HTSJ that has recently changed to a volume bound with the Journal of the Heat Transfer Society of Japan consisting mainly of Japanese articles. JTST covers a variety of fields in thermal engineering including heat and mass transfer, thermodynamics, combustion, bio-heat transfer, micro- and macro-scale transport phenomena and practical thermal problems in industrial applications.
