摘要
围绕多物理场耦合问题,基于连续介质假设,采用非结构化网格和有限体积方法开发多物理场耦合并行计算软件GTEA。该软件包括计算流体力学、结构应力波传播、流-声耦合和声-固耦合等4个功能模块。介绍GTEA前处理网格读取、网格格式转换、求解器开发等关键技术。通过柴油机缸内工作过程模拟、船舶水动力计算、自然对流与辐射传热耦合作用、流场动力噪声计算和结构-声耦合计算等5个典型应用展示该软件的应用能力和适用范围。
According to the coupling issue of multiphysics field, based on continuoua multiphysics field coupling computing software GTEA is designed using the unstructured mfinite volume metliod. The GTEA software consists of 4 functional modules, which are computational fluid dynamics,structural stress wave propagation,fluid-acoustic coupling, and acoustic-structure coupling. The key techniques are introduced such as the pre-processing mesh input, mesh fnumerical solver development. Five typical applications are selected to show the capabilities andapplications of the software, including the simulation of in-cylinder working process of dcalculation of ship hydrodynamics,the coupling effect of natural convection and radiation heat transfer,the dynamic noise calculation of flow field, and structure-acoustics coupling simulation.
