Opposite to other types of turbines for OWC wave energy converters, like the axial impulse or the Wells turbine, there is scarce information about radial impulse turbines. The interest in radial impulse turbine for wave energy is low because the available research on it shows lower efficiencies than the competitors. On the other hand, radial turbines present several advantageous features that make it a worthy option if the efficiency is improved. The purpose of the present work is to propose a new geometry, not focused on improving the rotor efficiency, but on reducing losses downstream of the rotor. This new design, taking previous geometries as a reference, was based on the classical 2-D angle computations optimizing the flow and blade angles for both inflow and outflow modes. After setting a balanced agreement between both modes, a numerical model with the new design was mounted on ANSYS Workbench which has allowed to speed up the whole process by using the specific tools set for turbomachines. Taking advantage of the simulation speed provided by the use of this model. A solidity optimization process was performed out on the new geometry to decide the required number of blades and vanes of the proposed turbine. Once, the turbine was well-defined, it has been compared concerning the previous turbine under both, steady and non-steady flow. The improvement has been remarkable, reaching a 10 % in steady efficiency and 6.7 % in non-steady efficiency with respect to the previous geometries.

与用于OWC波能转换器的其他类型的涡轮机相反，例如轴向脉冲式或Wells涡轮机，关于径向脉冲式涡轮机的信息很少。径向脉冲涡轮机对波浪能的兴趣很低，因为对它的现有研究表明其效率比竞争对手低。另一方面，径向涡轮具有几个有利的特征，如果效率得到提高，则成为值得选择的选择。本工作的目的是提出一种新的几何形状，其重点不是提高转子效率，而是减少转子下游的损耗。这项新设计以以前的几何形状为参考，基于经典的二维角度计算，可针对流入和流出模式优化流量和叶片角度。在两种模式之间达成平衡的协议后，在ANSYS Workbench上安装了具有新设计的数值模型，该模型通过使用用于涡轮机的特定工具集加快了整个过程。利用此模型提供的仿真速度。在新的几何形状上执行了坚固性优化过程，以确定拟议涡轮机所需的叶片数和叶片数。一旦对涡轮机进行了明确定义，就已经将其与以前的涡轮机在稳态和非稳态流量下进行了比较。相对于以前的几何形状，这种改进是非常显着的，达到了10％的稳定效率和6.7％的非稳定效率。利用此模型提供的仿真速度。在新的几何形状上执行了坚固性优化过程，以确定了拟议涡轮机所需的叶片数和叶片数。一旦对涡轮机进行了明确定义，就已经将其与以前的涡轮机在稳态和非稳态流量下进行了比较。相对于以前的几何形状，这种改进是非常显着的，达到了10％的稳定效率和6.7％的非稳定效率。利用此模型提供的仿真速度。在新的几何形状上执行了坚固性优化过程，以确定了拟议涡轮机所需的叶片数和叶片数。一旦对涡轮机进行了明确定义，就已经将其与以前的涡轮机在稳态和非稳态流量下进行了比较。相对于以前的几何形状，这种改进是非常显着的，达到了10％的稳定效率和6.7％的非稳定效率。
