Laboratory Experiments in Geodynamics

小行星9627891 PI建议进行实验室流体动力学实验，并应用于地球地幔和地核的流动。 PI将通过实验研究造成在上地幔和内核中检测到的地震各向异性的对流过程，还将研究受旋转和磁场影响的液态金属中的热化学对流，并将其应用于地球发电机。 将实验结果与磁对流的数值计算和外核的流型进行比较。 在对流，旋转和磁场的存在下结晶的固体镓的弹性和电各向异性的测量将与内核各向异性的观测作为测试的理论的内核的增长进行比较。 ***

9627891 Olson The PI proposes to conduct laboratory fluid dynamics experiments with applications to flow in the Earth's mantle and core. The PI will study experimentally the convective processes responsible for the seismic anisotropy that has been detected in the upper mantle and in the inner core, and will also investigate thermochemical convection in liquid metal subject to the influences of rotation and magnetic fields, with application to the geodynamo. The experimental results will be compared with both numerical calculations of magnetoconvection and with the flow patterns in the outer core. Measurements of the elastic and electrical anisotropy of solid gallium crystallizing in the presence of convection, rotation and magnetic fields will be compared with observations of inner core anisotropy as a test of theories for the growth of the inner core. ***
