两相三维射流空间不稳定性工具(2PJIT)是一种基于MatLab的通用软件,用于预测圆柱射流两相剪切流动中不稳定性的发展。该软件采用切比雪夫谱方法求解气液两相的线性化N-S方程,并考虑了界面约束条件。对于给定的一组输入频率,软件输出相应的波数、相关的特征向量/函数以及径向、方位和轴向扰动的空间增长率。
The two-phase 3D jet spatial instability tool (2PJIT) is a generalized Matlab-based software used to predict the growth of instabilities in two-phase shear flows involving cylindrical jets. The software solves the Linearized Navier–Stokes equation via the Chebyshev spectral method in both the liquid and gas phase along with the interfacial constraints. For a given set of input frequencies, the software outputs the corresponding wavenumbers, the associated eigen-vector/function, and the spatial growth rate for radial, azimuthal, and axial disturbances.
