| Abstract | 為了確保對洞窟的控制方式和控制量不會對壁畫和塑像有任何程度的損害,採用計算流體力學CFD技術對洞窟微環境引入的控製手段進行分析,結果表明主動抽風產生的氣壓以及壁畫表面的風速都比主動送風方式要小。在對第131窟所做的空氣交換率實驗證實了CFD的分析結果。因此主動抽風控制方式在中小洞窟對於減小空氣濕度以及降低二氧化碳濃度都具有良好的作用,同時對洞窟內的文物影響很小。
In order to ensure that the control method and control variable of the caves will not damage the murals and statues to any degree,CFD technology was used to analyze the control means of the cave’s micro environment.The analysis results show that active ventilation creates lower pressure and mural surface wind speed than active air supply.The air exchange experiment in cave 131 confirms the results of CFD analysis.It can thus be concluded that using the active ventilation control method in smaller caves is effective in reducing air humidity and decreasing the concentration of carbon dioxide,lessening the influence on the cultural relics in the caves. |
