Abstract:
The uneven distribution of the ambient temperature in a model of an infant incubator was demonstrated using the computational fluid mechanical (CFM) simulation of the air flow. A finite volume method of CFM calculation was performed on a three-dimensional (3D) model of an infant incubator including a model baby. The time course of the temperature distribution was computed solving the heat transfer equations simultaneously with the momentum equations. An uneven temperature distribution was observed for a long period (60 s) after the warm inflow was introduced into the incubator chamber. The temperature distribution was complex in 3D space and unsteady even after a long time, suggesting that it may take a considerable time to settle and may continue to be unsteady even if the inflow velocity is steady.

Mechanisms of Heat Transfer
Conduction, accounting for approximately 3% of body heat loss at rest, is the process of exchanging heat between molecules of two materials in direct contact. This can result in both heat loss and gain. For instance, when the body is submerged in water, which conducts heat 20 times more effectively than air, it can either lose or gain significant heat.
