# Heat transfer through cross flow heat exchanger with Ansys Fluent

Cross flow heat exchanger is a type of heat exchanger where the hot and cold fluids flow perpendicular to each other. In this configuration, the hot fluid which is steam, flows through pipes, while the old fluid which is water, flows around the pipes, exchanging heat through the tube walls. This arrangement facilitates the transfer of heat from one fluid to another. In this case study, the problem analyzed refers to cooling steam passing through steel tubes by using water as cooling medium. The water inlet velocity is 0.002 m/s and the temperature is 300 K. The hot fluid (steam) velocity is 0.001 m/s and the temperature is each tube is different (tube 1 – 400K, tube 2 – 410 K, tube 3 – 420 K, tube 4 – 430 K, tube 5 – 440 K, tube 6 – 450 K). The steam passes through 6 steel tubes. The results from the numerical simulations are presented and interpreted. This resource was created in collaboration with Faculty of Mechanical Engineering from Ss. Cyril and Methodius University in Skopje as part of the Ansys Funded Curriculum Program.
