Helical bundle heat exchanger support plate nonlinear vertical gradient thermal stress analysis. [HTGR]
This report summarizes a set of simplified structural design equations and parameters for the treatment of in-plane temperature gradients in preliminary design of high-temperature helical-coil tube-bundle support plates. The equations apply only to cases where slope changes occur during linear temperature gradients along the plate height. In addition, they are applicable only for plates whose aspect ratio W/L is between 1.5 and 7.0. It is intended that these equations be included in the overall structural feasibility investigations and calculations for determining a heat-exchanger size or envelope. The goal is to facilitate helical bundle heat-exchanger stress calculations during preliminary design phases. In addition, the simplified method of thermal-stress analysis has been substantiated by extensive finite-element calculations.
