项目摘要

With this award, researchers in UCLA's "SpinLab" will upgrade all the essential equipment in our world-unique geophysical fluid dynamics laboratory. These upgraded systems will allow the reseacher and his students to expand the experiments they carry out in order to better understand flows occurring in Earth's molten metal core that generate our planetary magnetic field. These upgrades will also provide students in the lab with training in the design and operation of leading edge laboratory systems. This award will also promote the continued expansion of the successful science outreach efforts, most recently developing new do-it-yourself experimental STEAM tools that can be used in classrooms with students of all ages.This award will allow the researchers to upgrade the capabilities of this world-unique experimental systems that simulate convection in Earth's core. Through ultrasonic Doppler techniques and stereoscopic laser velocimetry measurements, these enhancements will allows them to quantify new aspects of the flow fields that develop in the lab experiments (e.g., 2D velocity, vorticity and helicity maps), and to explore new experimental geometries that have not been previously interrogated. Further, the lab will update the heating and cooling systems, to produce even more strongly turbulent convective flows relevant to planetary (and stellar) conditions. These upgrades will allow the lab to conduct the next stage of experiments and provide bridges between geodynamo models and advanced models of planetary core turbulence.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

有了这个奖项，加州大学洛杉矶分校“ SpinLab”的研究人员将升级我们世界上唯一的地球物理动力学实验室中的所有必需设备。这些升级的系统将使研究人员和他的学生可以扩展他们进行的实验，以便更好地了解在地球熔融金属芯中产生我们行星磁场的流动。这些升级还将为实验室的学生提供领先实验室系统的设计和操作培训。该奖项还将促进成功的科学外展工作的持续扩展，最近开发了新的动手实验蒸汽工具，可以与各个年龄段的学生一起在课堂上使用。该奖项将使研究人员能够升级这个世界唯一的实验系统的能力，这些实验系统模拟了地球核心中的对流。通过超声多普勒技术和立体激光速度测量测量，这些增强功能将使他们能够量化实验室实验中发展的流场的新方面（例如2D速度，涡度和旋转型和螺旋映射），并可以探索以前未与众不同的新实验层次。此外，实验室将更新加热和冷却系统，以产生与行星（和恒星）条件相关的更强烈湍流的对流流。这些升级将使实验室能够进行下一个实验的阶段，并在地球模型和行星核心湍流的先进模型之间提供桥梁。该奖项反映了NSF的法定任务，并认为值得通过基金会的知识分子优点和更广泛的影响审查标准通过评估来获得支持。
