Abstract Introduction Problem Statement and Solution Methods Experimental and Numerical Results Conclusion Data Availability Acknowledgments The article presents the implementation of CFD/FEM approach for real oil tank of the gas turbine engine for the purposes of prediction of the component behavior under the local impact of a burner jet. The model takes into account heat and mass transfer problems as well as strength problems that are solved using a one way coupled fluid-structure interaction method. Results of the blind test simulation are compared and show good agreement with available experimental data.

These qualities make cross-linked polyethylene an excellent choice when tank integrity is critical. The structural integrity, heat resistance , and useful life in Materials - Corrosion and Corrosion AllowanceA tank wall required a 5 mm wall thickness for mechanical considerations. The designer has determined that the corrosion rate will be 0.4 mm/yr and the expected life of the tank will be 10yr. The total corrosion allowance is the corrosion rate per year (0.4 mm x 10 yr = 4 mm). The corrosion allowance is doubled to 8 mm as a safety consideration.
