ABSTRACT: Nowadays death of a newborn baby due to hypothermia is one of the vital
factors. To overcome the problem infant radiant warmer has been used in
hospitals which helps to prevent excessive heat loss of the baby by maintaining
a proper temperature. However, in practice, it is critical to regulating proper
thermal stability that is exactly required for a premature baby to conquer the heat loss problem. In this
study, we have established a computational model for heat transfer analysis
using the Finite Element Method. The heat transfer to the surrounding area skin
of newborn with the help of Infant Radiant Warmer (IRW) is simulated to study
the best range of light source to overcome the hypothermia. We simulate the
efficiency and effect of the infant radiant of the thermal radiation using
COMSOL Multiphysics program. For this simulation, we considered the distance
between the infant’s mattress and the bottom surface of the heater unit as 70 cm and
the heater power 500 watts, and 600 watts. We have investigated mattress
temperature, baby temperature and surface radiosity which are important to
understand to increase newborn baby body temperature. It is found that the
temperature of mattress raises up to 36 - 36.5
degrees Celsius and skin temperature raises up to 37 - 37.5
degrees Celsius.
