Abstract :

Heat transfer used is one of the most important and applicable natural phenomenon. Heat exchangers are the must applicable member in the chemical process and we can consider them in lots of industrial units. That provided the hat energy transfer between two or several fluid with different temperature. This operation can be done between liquid – liquid, gas - gas and gas - liquid. Heat exchanger will be used in order to cooling hot fluid and heating fluid with lower temperature or both of them. Many industries are acting in design kind of heat exchanger and many field with difference names in heat exchangers design are submitted by college and university. In this dissertation, heat transfer of heat exchanger shell and tube is simulated that it is U figure and the geometric of heat exchanger has been plotted and are meshed in GAMBIT software then are analyze in ANSYS FLUENT software. Finally the obtained answers are compare with designer is answers that have obtained in ASPEN software. The flow kind has been three-dimensional and turbulence that it has been used of turbulence model kω-sst. That should be noted the heat exchanger has been simulated by single phase.
