Abstract Based on the transient performance model for desalination of seawater based on the matrix algorithm, the desalination device is designed according to the evaporation condensation mechanism of falling film in horizontal tube, and its structure operation and operation principle are analyzed. Then, the differential equation of the transient heat-conduction problem of the seawater desalination device is constructed. On the basis of experimental data or numerical calculation results, the temperature field of structure at some time is selected to form the snapshots matrix, and a set of optimal eigenorthogonal decomposition bases is obtained by eigenorthogonal decomposition of the snapshots matrix. Finally, the finite-element discrete scheme of the nonlinear transient heat-conduction problem is reduced by using eigenorthogonal decomposition bases of the linear problem, and the lower-order ordinary differential equations of the reduced-order model for the nonlinear transient heat-conduction problem of the seawater desalination device are obtained. The ordinary differential equations of the reduced-order model are solved by solving the ordinary differential equations of the reduced-order model. The distribution of the temperature field at each time of the structure is obtained. The performance of the model is verified by numerical examples under the conditions of two-stage temperature-difference heating and only the top-level heating. The results show that the model has good accuracy and efficiency.
