  1. The research object of this thesis is a chip - array that is fixed on one of printed circuit boards ( pcb ), which are located in a forced air field ( forced convection ) in an electronic case ; and from the essential equations of airflow we can deduce the mathematical model of the turbulent flow ; then we can establish the finite element algorithm and apply the fe software to work out the equations of turbulent flow, finally we can use the software to display and analyse the field of flow and temperature

    本文以處于強迫空氣對流流場中的某pcb板及其板上的電子元件陣列作為研究對象，推導了紊流流場的數學模型，並建立了相應的有限元求解格式，應用有限元法分析軟體對該系統的紊流流場和溫度場進行了模擬分析：解算出pcb板上各電子元件的溫度分佈；並提出了用於求解系統風道特性曲線的cfd方法。
  2. The flow characteristics, distributions of current density and chemical components, and the performance of these two different designs are calculated and compared. the flow and mass transport characteristics are analyzed in detail, which indicate that strong forced convection is produced in the interdigitated flow field, which consist of dead - end gas channel that force the gases through the porous electrodes. results of comparison show that forced convection induced by the interdigitated flow field in the diffusion layer effectively enhances mass transport of reactants and products, thus leading to a higher cell performance and the limiting current density

    在傳統流道設計的pemfc中，反應物從流道到催化層的供應和生成物從催化層到流道的排出主要是以擴散為主，而在交叉梳狀流道設計中，以流動帶動的對流傳遞則占據了主導地位，而且這種以對流為主的傳遞機理大大提高了反應物和產物傳遞速率，從而有效地改善了電池的極限電流密度和極化性能等特性。
  3. In this thesis, a series of experiments are carried out to study the flow field in the hermetic cabins and also a mathematical modeling was built to simulate the flow of the cabins using the cfd software ? luent. that the convection on the ground include forced convection and free convection

    根據實際情況，建立切實可行的地面模擬技術，建成地面模擬實驗裝置，然後對其密封艙內的流動情況進行了地面實驗，並且對其中一個型號的密封艙建立了數學模型，用fluent軟體計算得到速度場。
