To respond this increasing technology demand, in this thesis, a molecular dynamics study on nano-scale fluid transport is performed. By introducing deformable polymer macromolecules in solution, our simulations systematically reveal the complex interaction of fluid transport with macro molecular dynamics at very small confined space. 针对这一实际工程需要,本论文采用分子动力学方法研究纳米尺度下流体的传输特性,特别引入聚合物大分子,系统模拟在小尺度上流体传输与生物分子的相互作用。
