摘要
海军工业已经整合了通过核过程产生的能量,因为这些过程中产生了大量的能量,例如,NS OTTO HAHN号船,它使用了一个由压水反应堆(PWR)产生能量的推进装置,该反应堆在核裂变过程中运行。此外,其他例子还有军舰和破冰船。为了了解这种类型的核推进装置的能量贡献,这项工作对压水堆反应堆进行了多物理分析,考虑到与铀棒接触的流体的湍流行为。最后,给出了沿燃料元件和出口喷嘴的流体速度场以及反应堆内部温度场的结果。
Multiphysics analysis of a pressurized water reactor for military ships
The naval industry has integrated the generation of energy through nuclear processes, due to the large amount of energy that is produced in these processes, for example, the ship NS OTTO HAHN, which used a propulsion plant with energy generated by a reactor of pressurized water (PWR), which operated under a nuclear fission process. Also, other examples are military ships and icebreakers. In order to know the energy contribution of this type of nuclear propulsion plants, this work carries out a multiphysics analysis of a PWR reactor, considering a turbulent behavior for the fluid that comes into contact with the uranium rods. Finally, the results of the fluid velocity fields along the fuel elements and the outlet nozzles are presented, as well as the temperature fields inside the reactor.
