Toroidal skeleton model of a high-porosity cellular material for modeling a supersonic flow around a cylinder with a gas-permeable frontal insert at an angle of attack

Toroidal skeleton model of a high-porosity cellular material for modeling a supersonic flow... Results of numerical simulations of a supersonic (M∞ = 7) flow around a cylinder with a gas-permeable frontal insert made of a high-porosity cellular material are reported. A toroidal skeleton model of a high-porosity medium is developed and implemented to describe air filtration in the gas-permeable insert. The aerodynamic coefficients of the cylinder model for various angles of attack (α = 0÷15°) are obtained. They are found to agree well with available experimental data, which confirms that the proposed skeleton model adequately describes the real properties of high-porosity materials. http://www.deepdyve.com/assets/images/DeepDyve-Logo-lg.png Thermophysics and Aeromechanics Springer Journals

Abstract

Results of numerical simulations of a supersonic (M∞ = 7) flow around a cylinder with a gas-permeable frontal insert made of a high-porosity cellular material are reported. A toroidal skeleton model of a high-porosity medium is developed and implemented to describe air filtration in the gas-permeable insert. The aerodynamic coefficients of the cylinder model for various angles of attack (α = 0÷15°) are obtained. They are found to agree well with available experimental data, which confirms that the proposed skeleton model adequately describes the real properties of high-porosity materials.
