To improve the efficiency of work and quality of life of human beings, the study of thermal comfort is essential. Thermoregulation of the human body is examined analytically in this study. The human body's steady-state heat balance model is used to design a mathematical model. The convective, radiative, respiratory, and evaporative heat transfer ar...

Natural convection cooling of an electronic component in an electronic device using water-based Fe3O4 magnetic nanofluids is studied under the presence of the magnetic field. The heated vertical electronic component in an enclosure type electronic device with a magnetic field source is used as a model for the study. Different samples of Fe3O4-water...

The present paper investigates the buoyancy induced flow and heat transfer in a square enclosure filled with Fe3O4/water magnetic nanofluid heated by mutually orthogonal heaters and symmetrically cooled by sidewalls under the influence of strong uniform magnetic field. The nanofluid is experimentally synthesized by two step method and the different...

In the present study numerical analysis of heat transfer is studied in an elliptical annulus with non-Newtonian nanofluids for different eccentricities under the laminar conditions. It was found that heat transfer rate increases on increasing the eccentricity and Reynolds number. The numerical analysis of the present problem requires simultaneous s...
