Abstract
Thermal boundary layer corresponds to a variation on the temperature field that occurs in a narrow region close to the wall of a rigid body when this is exposed to a fluid flow at a different temperature. Studying this phenomenon is important to the various industrial application, such as designing cooling systems for electronic components, capturing solar energy, geothermal reservoirs, and enhanced oil recovery. The present work aims to perform a characterization of the laminar thermal boundary layer considering a Newtonian fluid flow inside a round tube. In order to do that, it was developed a mathematical model using GITT (Generalized Integral Transform Technique), the obtained results allow to verify the temperature development inside the tube and therefore to show the characteristics of the boundary layer including its thickness in certain points.
