In this present study, heat transfer performance of a shell and tube heat exchanger used molten salt is analyzed by a computational fluid dynamic (CFD) programing. The model is prepared regard as a literature study that includes experimental results for validation. ANSYS 14.5 numerical package software is used in the solution of cases. The special heat transfer fluid, molten salt is used as fluid material that has been used between 360 degrees C -400 degrees C and 0,48 - 1,87 m3/h. The numerical results are compared with experimental results in literature and a good conformity has been achieved with considering limited numerical errors. In this study may be used in future studies developed numerical CFD models.
