Shell Balance Approach for One-Dimensional Biofluid Transport

Abstract

In the previous chapter, we took a macroscopic view for solving transport problems. The macroscopic approach is sufficient if you are interested in how the average transport variables change with time in a system. However, if you also want to know how transport properties such as mass, concentration, charge, velocity, or temperature vary with position (x, y, z), then it is necessary to use a microscopic approach. This allows the system of interest to shrink to an infinitesimally small volume surrounding an arbitrary point within the larger system.
