Linear static stress analysis of a heat exchanger design. 5 Load cases were considered for each design analysed, with varying loads being applied in each case, including thermal expansion and environmental loads such as wind. These loads were provided by the customer. In total, 9 design iterations were analysed for the heat exchanger. Stress linearisations were reported at a joint between a nozzle and header in the model, and compared against allowables in the relevant ASME Standard.
Linear Static stress analysis of a heat exchanger. Multiple load cases were analysed across several design iterations. Loads included nozzle loads, internal pressures, elevated temperatures and environmental loads such as wind. Stress linearisations have been reported for each load case, and compared to the allowables in the ASME standards.
Linear static stress analysis of a heat exchanger jig structure, with non linear surface contact. Multiple load cases were analysed, with the heat exchanger being held by the jig in different positions. Beam and Plate elements were used to represent the geometry. In total, 4 different designs were analysed, with the factor of safety and bolt forces being reported for each load case.
Steady state heat transfer and linear static stress analysis of a heat exchanger assembly, using temperature dependent material properties. The heat transfer analysis was completed first to obtain a temperature field of the assembly, which was then applied to the stress analysis. Multiple stress load cases were run with different load combinations considered. Stresses and displacements were reported for the design.
Linear static stress and design optimisation of a vessel window, subject to an internal pressure. The thickness of both the inner and outer windows was optimised so that it was as thin as possible without the stresses being above the design strength. A minimum allowable thickness for both windows in the design was recommended.
Stress analysis of diffusion bonded heat exchanger core subjected to pressure and thermal expansion. Report included extensive stress linearisation required to confirm compliance with pressure vessel code. Image shows a very small cut-out of the model.
Linear static stress, fatigue and modal analysis of a disk design. For the stress and fatigue analysis, a half model was used. Based on the results of the fatigue analysis, it was deemed the design has an infinite fatigue life. The first natural frequency was also above the minimum frequency required, proving the design’s viability.
