valve code

Simulation results show that compare to the rise cosine pulse, with the narrow main valve and the faster high frequency rolling and the better resisting of spectral spreading, the new type IJF code has better performance.

仿真结果表明：与传统的升余弦脉冲比较，新设计的IJF码型性能更加优越，表现为主瓣窄，高频滚降快，有效地抑制了频谱扩展。

The three-dimensional numerical simulation has been made on the steady flow field in the tangential inlet port-valve-cylinder with RNG k-ε turbulent model by using commercial code FLUENT under the conditions of two valve lifts.

使用FLUENT商业软件，采用RNG k-ε湍流模型，对稳定流动实验条件下，不同进气道角度时切向进气道-气门-气缸内的流场，在两种气门升程下进行了三维数值模拟；
