In order to increase the performance of a gas centrifuge, it is necessary to stabilize an axial flow inside the rotor. To this end, the computer simulation is significant. In this work, a specific solver (ICDB) was developed in OpenFOAM to simulate the gas flow in the rotor. Developing solver is important because OpenFOAM is a free and open source software. In order to check the accuracy of this solver, according to a study carried out by Shen Chun, a high-speed airflow is considered on a flat plate. To validate the ICDB, the results are compared with Fluent and Chun's findings. It is illustrated that the ICDB solver is in good agreement with other results. Then, using the ICDB solver and the fluent software, the uranium hexafluoride gas flow inside the axisymmetric rotor was simulated taking into account different drives such as thermal drive (wall and caps) and mechanical drive (scoop). The results are well modeled, and there is not much difference between the results of the ICDB and the fluent. The obtained results are shown the developed solver in OpenFOAM can be used for simulation the uranium hexafluoride gas flow inside the rotor.
