P.I. Webster, Donald (Georgia Tech) Proposal #: 0219519The PIs propose to develop a new apparatus to simulate oceanic turbulence in the laboratory. The work proposed is a one-year effort to complete the design, construct, and validate the apparatus. The proposed equipment is superior to traditional designs, such as grid-oscillating tanks, because of greater isotropy, improved homogeneity, increased simplicity, increased controllability, increased transportability, and reduced cost. The system consists of a cubic Plexiglas box with an actuator located at each corner. Each actuator alternatively forces fluid out of and draws fluid into a small hole in the box wall. This action induces a turbulent pulsed jet originating from each corner aimed at the box center; the net result of the eight actuators is a highly isotropic and homogeneous turbulent region in the volume surrounding the box center. This system is based on a previous apparatus constructed for use with gases. Once validated, the system will have broad application for research in physical and biological oceanography as well as fundamental fluid mechanics.

P.I.韦伯斯特，唐纳德（佐治亚理工学院）提案＃：0219519 PIS提议开发一种新的设备，以模拟实验室中的海洋湍流。提出的工作是为期一年的工作，以完成设计，构建和验证设备。所提出的设备优于传统设计，例如网格振荡的储罐，由于各向同性更大，均匀性的提高，简单性提高，可控性提高，可运输能力提高和成本降低。该系统由一个立方有机玻璃盒组成，该盒子在每个角落都有一个执行器。每个执行器都会迫使流体脱离，并将液体抽入盒子壁上的一个小孔中。这种动作引起了一个源自针对盒子中心的每个角的湍流脉冲喷射。八个执行器的最终结果是在盒子中心周围的体积中高度各向同性和均匀的湍流区域。该系统基于以前构建的用于与气体一起使用的设备。经过验证后，该系统将在物理和生物海洋学以及基本流体力学方面具有广泛的研究。
