The journal of Heat and Mass Transfer Research is an enabler of information exchange among mechanical, chemical, biomedical, nuclear, and aeronautical engineers, students, and researchers concerned with heat and mass transfer, thermal power, and fluid dynamics. Its focus is on the most recent original theoretical, experimental, and analytical research in the heat and mass transfer arena.  Subjects covered in Heat and Mass Transfer Research encompass the entire field of heat and mass transfer and relevant areas of fluid dynamics, including conduction, convection, and radiation, phase change phenomena including boiling and solidification, heat exchanger design and testing, heat transfer in nuclear reactors, mass transfer, geothermal heat recovery, multi-scale heat transfer, heat and mass transfer in alternative energy systems, Heat transfer in emerging technologies such as Micro-Electro-Mechanical Systems (MEMS), Micro-channels, Fuel cell, Bio- and Nano-technology,  Porous media, Ice formation, and Melting, Reactor design, Microreactors, Multiphase reactors, Multiscale modeling, Transport phenomena related to multiphase reactors; Gas-solid reactions, Heat transfer in machinery and welding operations, Ironmaking process, combustion.

Submissions from other fields of heat and mass transfer, and from other areas within the field of heat and mass transfer, are welcome. Papers are assessed only with regard to quality and their potential for fundamental and generic contribution to heat and mass transfer.
