Currently, for an engineering company remain competitive, is vital to reduce the time spent in execution projects in order to reduce costs (man - hour). In this context, this work aims to contribute with the time reduction in the analysis of non-isothermic three-dimensional flows, applying the AMR technique (Adaptive Mesh Refinement Location Technique) and Immersed Boundary, allowing the use of Cartesian mesh. The mathematical model and numerical solution was implemented in AMR3D code, in development at the Laboratório de Mecânica dos Fluidos ( MFLab ), designed for applications in multiphase flows with nonstatic boundaries. In a more simplified approach, this work deals with single-phase flow with static boundaries. Verification and validation tests for the energy equation are presented through manufactured solutions and flows in driven cavities. According to the results presented in this study, the mathematical and numerical models were satisfactory for the solution of the energy equation for incompressible, non-isothermal flows with constant physical properties, allowing the development of future works considering non-isothermic two-phase flows with non-static boundaries.
