According to geologic model of unsteady groundwater flow in heterogeneous medium and adopting the finite difference solution, the direction and strength of oil gas migration can be quantified.
根據(jù)非均勻各向異性地層的非穩(wěn)定的地下水流動模型，采用有限差分法求解，可以定量判斷油氣運移的方向及強度。
Based on the above study, a three-dimensioned unsteady heat transfer model of U-type UCHE was established, which took different thermal properties of soil layers and groundwater flow into account.
在上述研究基礎上，圍繞埋地換熱器與周圍土壤的換熱過程，考慮沿深度方向土壤層之間熱物性的不同以及地下水流動等因素，建立了垂直U型埋地換熱器三維非穩(wěn)態(tài)數(shù)值傳熱模型。
