Abstract

A flow of a viscous gas from a nozzle, which oscillates around an axis perpendicular to the axis of symmetry of the nozzle, is considered. The study of the gas-dynamic process is based on the numerical solution of the two-dimensional and three-dimensional Navier-Stokes equations, written in a non-inertial reference frame associated with the nozzle and using the relative components of velocities and accelerations. The flow characteristics in plane and axisymmetric nozzles and jets exhausted from it are obtained using a high order of accuracy method.A flow of a viscous gas from a nozzle, which oscillates around an axis perpendicular to the axis of symmetry of the nozzle, is considered. The study of the gas-dynamic process is based on the numerical solution of the two-dimensional and three-dimensional Navier-Stokes equations, written in a non-inertial reference frame associated with the nozzle and using the relative components of velocities and accelerations. The flow characteristics in plane and axisymmetric nozzles and jets exhausted from it are obtained using a high order of accuracy method.

喷嘴振荡运动过程中气体动力学效应的研究

考虑从喷嘴流出的粘性气体绕垂直于喷嘴对称轴的轴振荡。气体动力学过程的研究是基于二维和三维Navier-Stokes方程的数值解，这些方程写在与喷嘴相关的非惯性参照系中，并使用速度和加速度的相对分量。采用高精度方法得到了平面和轴对称喷嘴内的流动特性以及从中排出的射流。考虑从喷嘴流出的粘性气体绕垂直于喷嘴对称轴的轴振荡。气体动力学过程的研究是基于二维和三维Navier-Stokes方程的数值解，这些方程写在与喷嘴相关的非惯性参照系中，并使用速度和加速度的相对分量。采用高精度方法得到了平面和轴对称喷嘴内的流动特性以及从中排出的射流。
