Abstract or Summary
  • A numerical technique is presented for solving the gas dynamics of a pulsating combustor. The computer solution which is developed follows directly from the fundamental conservation laws applied to discrete volumes rather than attempting either to finite difference the resulting partial differential equations, or to apply the Method of Characteristics. The integration procedure closely relates to the physical model, and various types of boundary conditions and diffusion effects can be included. The addition of diffusion terms also helps to dampen oscillations caused by near discontinuities in the flow field, spreading these discontinuities over several cell widths. Combustion processes are included in the computer solution by following the concentrations of the injected fuel and the oxygen aspirated from the atmosphere, and computing the energy released when the fuel ignites. The results obtained using this technique show reasonable agreement with those obtained using the Method of Characteristics, and with actual test data.
