Chapter 6 SOLUTION OF VISCOUS-FLOW IntroductionTHE previous Chapter contained derivations of the relationships for the con-servation of mass and momentum|theequations of motion|in rectangular,cylindrical, and spherical coordinates. All the experimental evidence indicatesthat these are indeed the most fundamental equations of uid mechanics, and thatin principle they govern any situation involving the ow of a Newtonian , because of their all-embracing quality, their SOLUTION in analyticalterms is di cult or impossible except for relatively simple situations.
examples, illustrating the above steps for solving viscous-°ow problems. Example 6.1|Flow Between Parallel Plates Fig. E6.1.1 shows the °ow of a °uid of viscosity „, which °ows in the xdirection between two rectangular plates, whose width is very large in the zdirection when compared to their separation in the ydirection. Such a situation ...
