Consider Graetz’s problem, discussed in Section 4.5. Assume plug flow regime, i.e., a uniform velocity distribution. The resulting problem is sometimes referred to as the simplified Graetz problem. Using the separation of variables technique, derive an analytical solution for the temperature profile as a function of axial and radial coordinates.
