( 1 )从navier - stokes方程上经过假设和简化得到的三维潮流控制方程，以vincenzocasulli法，采用半显半隐差分格式，建立了一个三维潮流数值模型。 - According to actual situation of production wells , external boundary conditions and coupled inner boundary conditions between welibore and adjacent rocks , welibore and production zones , adjacent rocks and production zones are constructed , and an alternate direction implicit finite difference algorithm ( adi ) is used to solve temperature models
根据生产井的实际情况，构建起外边界条件以及井筒与围岩、井筒与产层、围岩与产层之间的耦合内边界条件，采用交替方向半隐式有限差分方法( adi方法)求解所建立的井下温度场模型。 - Though adopting the - coordinate transformation in the control equations and mode - splitting technique , the external mode ( surface gravity waves ) is solved by the improved double - sweep - implicit finite difference method ; the internal mode ( internal gravity waves ) untilizes the eulerian - lagrangian method , which improves the implicit - difference scheme for the vertical direction . the newly developed 3d numerical tidal model with implicit scheme has been successfully applied in the radial sandbanks area
