Thermal state of a conical antenna used for big data transfer was determined in this work. Its cooling is provided through porous media saturated with water-based copper nanofluid (NF) whose volume fraction varies in the 0% (pure water) −10% range. Otherwise, the ratio between the thermal conductivity of the highly porous material and that of the fluid base (water) varies between 4 and 41.2. The solution is obtained by means of 3D numerical approach based on the volume control method using the SIMPLE algorithm in the large 3.32×105–6.74×107 Rayleigh number range. The average temperature of the antenna can be determined with the correlation proposed in this work for any combination of the thermal conductivity ratio, volume fraction and Rayleigh number. This new and original correlation makes it possible to determine the optimal values of these three influencing parameters to ensure the correct antenna’s operation.

纳米流体饱和多孔介质冷却锥形天线的热态

在这项工作中确定了用于大数据传输的锥形天线的热状态。它的冷却是通过饱和水基铜纳米流体 (NF) 的多孔介质提供的，其体积分数在 0%（纯水）中变化-10%范围。否则，高度多孔材料的热导率与流体基体（水）的热导率之比在 4 和 41.2 之间变化。解是通过基于体积控制方法的 3D 数值方法获得的，使用 SIMPLE 算法在大3.32×105–6.74×107瑞利数范围。对于热导率、体积分数和瑞利数的任意组合，可以使用本文提出的相关性来确定天线的平均温度。这种新的和原始的相关性使得确定这三个影响参数的最佳值成为可能，以确保正确的天线操作。
