Our article on the using of scaling analysis as a tool for the validation of CFD results appears in the journal of Thermal Science and Engineering Progress
In this article, we proposed scaling analysis as a simple approach to replace experimental measurements to validate CFD results. In fact, we used scaling analysis to validate the simulation results due to insufficient experimental results.
The journal bearing housing of a gas turbine engine was studied in this work. The authors considered the influences of the revolution speed of the rotor on the velocity, pressure and temperature distribution of the bulk oil at fixed inlet velocity and inlet temperature. First of all, we performed a CFD simulation on the fluid flow and heat transfer in the bulk oil of the bearing housing using COMSOL 6. Then, MATLAB R2022a was used to model scaling analysis results. Finally, the CFD simulation results were compared with the final equation obtained by the scaling analysis.
Overall, we found that the CFD simulation developed in this work is physically valid. We showed an agreement between the simulation results and the governing equations of the system, especially at higher rotational speeds.
