The main objective of this paper is to present numerical modeling and assessment of heat transfer in neonatology. In the present study, numerical simulation is performed over a simplified infant model with specific boundary conditions in a closed chamber. The proposed approach is based on three‐dimensional (3D) computational fluid dynamics (CFD) simulation to capture the combined effect of air flow and heat transfer phenomena: natural convection and radiation heat transfer taking place around an infant and radiant lamp. A 3D model is numerically investigated using the commercial CFD package StarCCM+. The results presented are compared and found to be in qualitative agreement with the results available in the literature and published measurement data.
