"Drug delivery to inside of the tumor is the important problem. The dynamics of drug delivery is presented here. Previously and particularly for directed delivery, a stirred tank model has been used, which appears to have worked well when compared to experiments. However, the stirred tank models do not include all the mass transfer resistances and towards that end we have used a distributed system called Krogh cylinder. This study focuses on the Krogh cylinder model simulation, both on the fluid flow and the mass transfer. The capillary network is broken down into cylindrical cells, each containing a capillary and appropriate amount of extravascular tissue. An organ is built with several of these connected in parallel. These models use the experimental data and apply many formulations, such as dynamics, through the capillary membrane, through the porous media. The result emphasizes convective mass transfer, in major disagreement with Krogh cylinder models available so far. It predicts the flow more closely to obtain a higher amount of convection in keeping with non-quantitative discussions in physiology. The equations of motion, continuity and conservation of species to obtain pressure distribution and drug distribution"--Abstract, page iv.
