Abstract

The following paper is part of a comprehensive study which aims to investigate the potential of a linear air amplifier as an alternative to rotary fans in data centre cooling. This paper aims to expand the understanding of the aerodynamic characteristics of the device as parameters such as nozzle width and diffuser angle are altered, as well as validating a numerical model of the device. A modular testing facility was created to allow the device to be investigated under different conditions. The conditions were then replicated in a numerical model using Ansys Fluent, the results of both the numerical and experimental measurements were compared to determine the validity of the numerical model. The numerical model followed the same trends as the experimental measurements when input pressures, nozzle widths and back pressures were varied. It was found that the numerical model was within ±11% of the experimental data, therefore validating the model.

数据中心服务器中可调空气放大器替代风扇的数值研究

以下论文是一项全面研究的一部分，该研究旨在调查线性空气放大器作为数据中心冷却中旋转风扇的替代方案的潜力。本文旨在扩大对喷嘴宽度和扩散角等参数改变时该装置气动特性的理解，并验证该装置的数值模型。模块化的测试设备可以在不同的条件下进行测试。然后利用Ansys Fluent将上述条件复制到数值模型中，并将数值测量结果与实验测量结果进行比较，以确定数值模型的有效性。当输入压力、喷嘴宽度和背压发生变化时，数值模型的变化趋势与实验结果一致。结果表明，数值模型与实验数据的误差在±11%以内，验证了模型的正确性。
