The impact of triangularity on edge plasma transport and turbulence is addressed from full 3D turbulence simulations performed with TOKAM3X. Flux driven fluid simulations are run on analytical magnetic equilibria generated with positive and negative triangularity $\delta$ in a bottom limiter configuration. The conservation of the energy is assured by the increase of the bottom limiter radial position from $\delta >0$ to $\delta <0$. Changing the triangularity impacts both the plasma equilibrium and the turbulence. In particular, negative triangularity leads to a reduction of the density and electron temperature decay lengths in agreement with the literature. Concerning the turbulence, in all the simulations, it remains ballooned with an enhanced level of fluctuations at low field side in comparison to the high field one. Moreover, no clear trend is visible on the relative level of fluctuations of both density and electron temperature in the CFR whereas an enhancement (resp. reduction) is visible in the scrape-off layer at the low field side midplane for the negative (resp. positive) triangularity simulations. This behaviour differs from TCV and DIII-D measurements which show the benefit of negative triangularity in terms of turbulence reduction and increased confinement. However, no conclusion is drawn from our preliminary study concerning the impact of triangularity on the turbulent transport. Change in triangularity impacts many simulation control parameters, as in the experiments, and that the analysis of its impact alone on the dynamics of the plasma is not obvious in this configuration.

通过使用TOKAM3X进行的完整3D湍流仿真，可以解决三角形性对边缘等离子体传输和湍流的影响。磁通驱动的流体模拟是基于具有正负三角形的解析磁平衡进行的$\delta$在底部限制器配置中。通过增加底部限制器的径向位置，确保了能量的节约$\delta >0$ 至 $\delta <0$。改变三角形会影响等离子体平衡和湍流。特别地，负三角形导致与文献一致的密度和电子温度衰减长度的减小。关于湍流，在所有模拟中，与高场相比，它在低场侧的膨胀程度一直保持增加。此外，在CFR中密度和电子温度的相对波动水平上没有明显的趋势可见，而在负电场的低场侧中平面的刮擦层中可见增强（减少）。正）三角形模拟。此行为与TCV和DIII-D测量结果不同，TCV和DIII-D测量结果显示出负三角形性在减少湍流和增加封闭性方面的优势。然而，从我们的初步研究中没有得出关于三角形对湍流传输的影响的结论。三角形的变化会影响许多模拟控制参数，如在实验中一样，在这种配置下，仅对其影响对等离子体动力学的影响进行分析是不明显的。
