In it we model the cooking of a roast by solving the transient heat conduction equation in a finite, axisymmetric cylindrical geometry. Because the solution of these differential equations by analytical means is challenging for all but the simplest configurations, the numerical results have been graphed in non-dimensional form and the resulting charts have been used routinely for the past three quarters of a century. (Solution of the third internal flow scenario, the combined-entry length problem, while certainly feasible, requires the solution of the axial momentum and continuity equations, in addition to the energy balance equation solved here.) We share an example of a heat exchanger in this video to outline the modeling steps for creating a realistic simulation of nonisothermal flow.
