numerical flow simulations can also provide information which is difficult to obtain experimentally . an example is the prediction of the flow separation areas inside the flow channel 數(shù)值模擬還能提供實驗測量難以獲取的流場信息,一個典型的例子是流道內(nèi)部分離區(qū)域的預(yù)測。
Abstract : based onmethods of foreign countries of using wi nd tunnel test and numerical flow simulation, optimum nose a nd tail shapes ofhigh-speed trains are studied to achieve optimum aerodynamic performance so as to efficiently reduce the influence of theaerodynamic phenome na on the train operation and the environment . research results of foreign countr ies are introduced 文摘:針對國外利用以風洞模型模擬試驗和以流場數(shù)值模擬計算為主的方法來尋求高速列車最佳的頭尾部形狀,使列車的綜合氣動性能最佳,從而有效地降低空氣動力學現(xiàn)象對列車運行和周圍環(huán)境的影響進行了探討,介紹了國外在此方面取得的主要成果。
