The behaviour of the field-ion microscope: A gas dynamical calculation

Surface Science, 1970
Abstract With the aid of a simple dynamical theory, the particle distribution in the tip region of the field-ion microscope is calculated. From this distribution a number of important properties of the field-ion microscope are computed, such as the field and temperature dependence of the total ion current to the screen and of the current from ...

Calculations of gain and power output for a gas-dynamic laser

IEEE Journal of Quantum Electronics, 1972
Detailed calculations of the coupled equations of nonequilibrium flow and the relevant molecular energy-exchange processes, have been carried out for a continuously operating CO 2 gas-dynamic laser system. Power outputs of about 100 kW/m length of nozzle throat at 1 percent efficiency with a small signal gain of 1 m-1are predicted.

An algorithm for calculating two-dimensional problems of gas dynamics in Lagrangian variables

USSR Computational Mathematics and Mathematical Physics, 1985
Abstract The numerical solution of two-dimensional equations of gas dynamics is investigated in a Lagrangian system of coordinates on tetragonal nets. One of the algorithms which prevent the formation of twisted cells is considered. However, the rearrangement of the difference net which arises during this process does not lead to a redistribution of ...

Developing Methods for Calculating Gas-Dynamic Parameters in Launch Canister During the Missile Launch

2019
Based on the analysis of various methods for modeling gas-dynamic processes, a methodology has been developed for calculating the main parameters in the launch canister, taking into account the heat exchange processes. The development of the technique includes the choice of physical and mathematical models of gas-dynamic processes in the launch ...
