AIP Conference Proceedings Vol. 1799. P. 060012-1-060012-8Abstract: At the present study calculation methodology of gas dynamics equations in ramjet engine is presented. The algorithm is based on Godunov`s scheme. For realization of calculation algorithm, the system of data storage is offered, the system does not depend on mesh topology, and it allows using the computational meshes with arbitrary number of cell faces. The algorithm of building a block-structured grid is given. Calculation algorithm in the software package “FlashFlow” is implemented. Software package is verified on the calculations of simple configurations of air intakes and scramjet models.
