Macroscopic Approach for Biofluid Transport



The macroscopic approach to biofluid transport is used to analyze fluid flow in the system as a whole. This is in contrast to the microscopic approach that we will describe in Chap. 6, which is used to predict spatial variations of shear stress, pressure, and velocity within the fluid. The macroscopic approach is appropriate when we are not interested in the spatial variations within the system, but instead are interested in average transient values or output values. Common objectives of the macroscopic approach are to find the rate of accumulation of fluid in the system, the fluid flow into or out of the system, or the forces exerted by the fluid on the system. These objectives are accomplished by applying general conservation principles to the fluid in the system.
