Moreover, not only the thermal efficiency increase, but also the energy costs for heat-transfer pumping have a great significance. Therefore, the heat transfer intensifiers in the aerospace field are evaluated by the integrated index: thermal-hydraulic efficiency. For today, a wide variety of heat exchange intensifiers was developed. The drop-shaped intensifier that has streamlined aerodynamic shape, to reduce hydraulic losses for heat-transfer pumping is considered in this work. This paper presents the results of numerical modeling of heat transfer process using drop-shaped intensifier. Also there is given the comparative analysis of thermal efficiency of drop-shaped intensifier with ring intensifiers and smooth pipes, as well as the comparison of hydraulic resistance increase. The researches were carried out at a turbulent flow in the range of Re numbers from 3000 to 80000. The use of drop-shaped intensifiers can improve thermal efficiency in the whole range of studies, compared to smooth pipes, at a moderate growth of hydraulic resistance over the entire range of Re numbers.
