In 1958 Siegel derived a thermal-entry-length integral solution for laminar flow in circular tubes with an arbitrary wall heat flux. From this a solution for a step-varying flux is derived. The objective of this research was to obtain experimental data to verify the accuracy of the above solution. The steps used were a good approximation of the sinusoidal heat flux, which exists along the cooling tube in nuclear reactors. The experimental results fell above the theoretical solution, the average difference being 10.9 percent. Thus, the step-varying wall heat flux solution may be used for the design of cooling systems within that uncertainty.
