The establishment of a supersonic one-dimensional flow of a dual-temperature, partially ionized plasma is investigated in the channel of a disk-MHD generator, taking account of nonequilibrium ionization and recombination reactions. A detailed formulation of the problem is given in [1]; flows are considered in the absence of ionization and recombination reactions and in the case of equilibrium reactions.Moscow.

Fountain viscous fluid flow arising during filling a plane channel is investigated. A finite-difference method is used to solve the problem of time-dependent nonisothermal flow taking mechanical energy dissipation, temperature dependence of the viscosity, and the presence of a free boundary into account. The results of parametric investigations of kinematic flow characteristics as functions of dimensionless constitutive criteria are given. 相似文献

The interaction between a transient cylindrical acoustic wave and a cylindrical piezoelectric transducer with sectioned electrodes
is considered. The solution is obtained using the integral Laplace transform with respect to time (in the form of natural-mode
series). In going to the space of originals, the problem is reduced to integral Volterra equations. The results of calculation
are presented for various angular dimensions of the electrode sections and various distances from the wave source to the piezoelectric
transducer.

The vibration problem of a viscoelastic cylindrical shell is studied in a geometrically nonlinear formulation using the refined
Timoshenko theory. The problem is solved by the Bubnov–Galerkin procedure combined with a numerical method based on quadrature
formulas. The choice of relaxation kernels is substantiated for solving dynamic problems of viscoelastic systems. The numerical
convergence of the Bubnov–Galerkin procedure is examined. The effect of viscoelastic properties of the material on the response
of the cylindrical shell is discussed. The results obtained by various theories are compared. 相似文献
