| 摘 要： | 为研究Navier-Stokes方程中对流项对粘性流注射模拟结果的影响,在基于矢量化显式算法模拟软件中加入对流作用项.应用修正后的软件模拟两个典型的注射填充过程的算例,并与相应的实验比较.对模拟和实验结果的比较表明,对流项对粘性流注射填充过程和的其中的自由表面形状的模拟结果影响可以忽略.

| Abstract: | To evaluate the effect of an advection term in the Navier-Stokes equation in simulation of the viscous injection flow,the advection term was added in the software that is based on vectorial explicit algorithm.Two typical examples were chosen to test the results of simulation,which were then compared with those by relevant experiments.Comparison of the results obtained by simulations and experiments shows that that the advection term has little effect on the results of injection process simulation and on those of free surface shapes in viscous flow injection. |
