21 Which behaviour of the particles in a gas is incorrect? C A The particles are very far apart. B The particles move at high speeds. C The particles are arranged in regular patterns. D The forces of attraction between the particles are negligible. 相关知识点: 试题来源: 解析 C 反...
The rate at which particles carried in a flowing gas are deposited on a cold surface by thermophoretic movement is studied theoretically. Some exact deductions from the coupled equations for the temperature ( T) and particle concentration ( C) in the moving fluid show that, in cases in which ...
3 are consistent. Some deviations above the statistical error are visible, in particular for the tug particle (dotted line in Fig. 4c), due to overfitting the parameters, when the delay function is not explicitly taken into account. This is confirmed by a more general fit, which minimises ...
The process described herein comprises the mixing of a chilled gas into a stream of gas-suspended particles. Preferably the chilled gas is the same as the gas in which the particles are suspended and the particles are electrostatically charged. A novel device is described which provides a chamber...

A cold gas spraying method and device, whereby the sprayed particles are accelerated in a gas flow. A powder tube and an outer nozzle body together form a Laval nozzle that produces high gas flow velocities. The injection of the sprayed particles occurs in the divergent section of the Laval ...

System for charging particles entrained in a gas stream A system for charging dust and the like particles entrained in a gas stream and which are to be electrostatically precipitated. An emitter electrode is disposed in the gas stream for producing ions of one polarity which charge particles .....
Second, the particles must have been transported in a gas-ash dispersion (observed in ash-laden jets during the eruption and feeding the intermittent gas-ash plumes that characterise the hybrid explosive-effusive eruptive style; Fig. 1c–e). Third, the fine particles must have sintered rapidly ...
