| description | ObjectiveThe thermal comfort of a ship's cabin has an important influence on the life and work of the crew. However, it takes a long time to design the air supply parameters using experimental research and the traditional numerical simulation trial method. Therefore, an inverse design method based on proper orthogonal decomposition (POD) is applied to the design of air supply parameters in a typical cabin. MethodIn this paper, a three-dimensional numerical model is established using the computational fluid dynamics (CFD) method. After obtaining the results of the flow field, temperature field and concentration field, combined with the inverse design method based on POD, the optimal thermal comfort and minimum pollutant concentration in the breathing zone of a nine-person cabin are taken as the optimization objectives. ResultsThe results show that the inverse design method based on POD can be used for the inverse optimization of multiple parameters and objectives. Compared with the traditional algorithm, it can save time by more than 90% and greatly improve the design efficiency of the transmission of cabin air supply parameters. ConclusionsThe POD method can be applied to the design of a ship's living quarters. The appropriate range of air supply parameters obtained by reverse design can provide references for the selection of the air supply parameters. |
