新型高效清洁氢火箭发动机的计算机辅助设计需要数学工具来对火箭燃烧室中氢氧组分的混合和化学反应进行超级计算机模拟。本文给出了计算机程序开发、验证和验证的结果，使模拟氢燃料在火箭发动机中的点火和燃烧非定常过程成为可能。发展了由于累积误差而对非定常气体动力学工作循环进行限制的超级计算机模拟。
Computer aided design of new effective and clean hydrogen rocket engines needs mathematical tools for supercomputer modeling of hydrogen–oxygen components mixing and chemically reacting in rocket combustion chambers. The paper presents the results of computer code developing, verification and validation, making it possible to simulate unsteady processes of ignition and combustion of hydrogen fuel in rocket engines. Restrictions on unsteady gas dynamics working cycles supercomputer simulations due to accumulations of errors are developed.
