Development of a Fog-Liquefier Composed of Wire and Rod Electrodes

在我们北部的太平洋沿岸，我们有一种周期性的极冷的东风，叫做“山口风”，它经常造成浓雾。由于它伴随着低温和缺乏阳光，许多农作物经常遭受严重的寒冷天气破坏。此外，由于浓雾造成的能见度低给所有的交通服务造成了严重的麻烦。为了采取措施，我们最近开发了一种叫做静电雾化器的人工消雾器，不仅在我们的实验室里，而且在户外也取得了良好的效果。然而，由细小的介电极组成的装置容易受到大风的影响。我们的报告描述了改进型模型的基础研究，将细网状电极换成了棒状电极。从基本实验中我们得到以下三个结果，认为它们是由离子风引起的。电极排列的效率是网状电极排列的几倍。粗棒的效率并不总是比细棒的效率高。在实验中，当离子风的速度与雾流的速度几乎相同时，可以观察到最大的液化速率。在实验中，我们将丝状电极和棒状电极布置成一条线来辅助雾流。我们打算进行实验，以检验我们应该选择上述类型的电极布置还是锯齿形电极布置。电场分布和离子风流也是需要分析的问题。

Along the Pacific Coast in our northern regions.we have a periodic very cold east wind called "YAMASE wind" which results frequently in a dense fog.As it is accompanied by low temperatures and by lack of sunshine, many crops have frequently suffered serious cold weather damage.In addition, poor visibility due to dense fog has caused serious troubles to all traffic services.In order to take countermeasures against such troubles, we have recently developed an artificial for-eliminator called the electrostatic fog-liquefier and obtained good results not only in our laboratory but also in outdoors.The apparatus composed of fine meshelectrodes, however, tended to be affected by a strong wind, so it needed frequent mending.Our report describes basic researches on development of the modified model, in which we exchanged fine mesh electrodes for rod ones. From the fundamental experiments we getfollowing three results, and consider they are caused by ionic windEffciency of rod eiectrode arrangement is several times as that of the mesh electrode arrangement.A thick rod is not always more efficient that a thin rod.The maximum liquefied rate is observed in case of almost the same veiocity of the ionic wind as that of the fog flowIn experiments we arranged wire electrodes and rod ones in a line aiong the fog flow.We intend to make experiments to examine which of electrode arrangements of above mentioned type or zigzag one we should choose.Electeic field distributions and ionic wind flows are also problems to be analyzed.
