device
For example, for a typical MHD device [1] with characteristic length 0.1 m of the working region, velocity 1 m/sec of the medium, and magnetic induction 1 T (the medium is molten sodium at temperature 330°C) the Alfvén number is A ~- 900.
      
In the first 90μsec the proposed device is insensitive to the high internal gas pressure.
      
It is shown that the efficiency of the EHD device can be improved if in the fluid the spatial process of ion formation is retarded, while the recombination process is intense.
      
The flow of a free jet of polymer solution or melt between a nozzle supplying fluid at a constant flow rate and a takeoff device in the form of a uniformly rotating roll is studied.
      
Calculation of the thrust of a wave-powered marine propelling device
      
A scheme for calculating the thrust of a wave propelling device with limiters is proposed.
      
The conditions of optimal outflow of the active (primary) and passive (secondary) jets from the device under consideration are obtained by solving the variational problem of maximum average thrust realization.
      
Study of the Effect of the Depth of the Cavity of a Braking Device on the Aerodynamic Drag of a Model in Transonic and Supersoni
      
Models of a braking device (sphere) were connected with a load (frustum of a cone) by means of shrouds.
      
The dependences of the aerodynamic coefficients Cx and Cy on the angle of attack α were obtained for different relative dimensions of the load and the braking device, shroud lengths, and Mach and Reynolds numbers.
      
A new method of pumping a fluid through a microchannel device using a gas bubble-piston, set in motion by the thermocapillary force induced by a light beam, is proposed.
      
The use of both X- and Y-oriented double crystals as Q-switches in order to combine large electro-optic coefficients and low quarter-wave hold-off voltages with excellent thermal stability of the device is considered.
      
Furthermore, the system instability, arising at the so-called pull-in voltage and corresponding to the on-off transition of the device, is also quantified.
      
Iron nanoparticles were synthesized without a chilling device in a condensation system of gases vaporized from iron pentacarbonyls as starting precursors.
      
The magnetic properties and the buildup kinetics of the photolysis products of crystalline 2,4,6-triazido-3,5-dichloropyridine at temperatures of 2-300 K were studied with the use of a superconducting quantum interference device (SQUID).
      
It was found that oxygen at the fabrication steps affects in different manners the formation of open-circuit voltage and the performance of the device.
      
The results are given of new measurements of shock compression of porous copper specimens in a hemispherical measuring device at megabar pressures.
      
A mathematical model of heat and mass transfer in a metal-hydride hydrogen storage device is suggested.
      
It is demonstrated that, under the operating conditions of the metal-hydride device being treated, the orientation of the module has a marked effect on the rate of absorption and integral characteristics of the storage device.
      
The developed mathematical model and numerical codes are used to estimate the sensitivity of thermomechanical reading of data with the device structure filled with various inert gases such as helium, neon, and argon.
