查询词典 sound waves

A 9 -Bit square lattice gas model with temperature was introduced. We fulfilled an acoustic driver using Monte Carlo Method. Using this driver to generate plane waves, a standing sound wave was established in a two\|dimensional pipe.

Fluidization and Sounding Pressure Characters Experimental Research on Pulsating Fluidized Bed After verifying experimentally the Rijke type self-exciting pulsating fluidized bed combustion, under different operating conditions (different empty cross-section wind speed and inaction bed height), experimental research the oscillation characters of sounding pressure in the pulsating fluidized bed. The results indicate that the sound characters in the Rijke type self-exciting pulsating fluidized bed combustor are the same with it in the Rijke type combustor, the pressure in the combustor oscillate up and down in the sinusoidal manner and the pressure is the superposition of the multiple harmonic waves.

脉动流化床流化与声学压力特性实验研究在实验验证了Rijke型自激脉动流化燃烧概念后，在不同运行条件(空截面风速、静止床层高度)下，实验研究了Rijke型自激式脉动流化床的声压振动特性，研究结果表明：脉动流化床内建立起的声波特性和Rijke型脉动燃烧器内的一样，各点压力呈正弦规律上下振动，且压力是基波幅值最大的多次谐波的叠加。
