Development of New Social System Utilizing Natural Energy-Model Experiment

本研究的最终目的是将水循环所涉及的自然能量融入我们的日常生活。具体地说，本文试图利用实验田的模型验证到目前为止所进行的野外实验的测量结果。(1)构建了一个基于直线运动基座的5自由度铰接式机器人测量系统。机器人抓住传感探头或风速计，测量模型中每个格点上的风速。开发了一个软件系统，使我们能够提前检查模型和探头的避让情况。(2)建立了1：2000的棒球场模型。对处理后的污水喷洒时风速矢量和温度变化的检测进行了尝试。喷洒效果的模拟是通过开启和关闭放置在钻石场上的薄膜加热器上的电源来实现的。由于所用传感装置的分辨率较低(0.1m/S和0.1Lm/ﾟC)，无法检测到测量的大小差异。为了验证环境降温的效果，在金泽理工学院的一个场地上，对一栋六层长织机的简易建筑前的人行道进行了洒水。在海拔0.5米，风速0.5米/S，观测到气温下降0.5ﾟC-LﾟC。建立了该情况下的计算模型，并进行了数值分析。在海拔0.5m处，环境温度下降了2.3万ﾟC。

The ultimate object of the present study is to incorporate the natural energy involved in the circulation of water into our daily life. Specifically in the present report is tried to verify the measurements of field experiments practiced so far using the models of experimented fields.(1) A measurement system was constructed with a 5-degree-of--motion articulated robotarm put on a linear motion base. The robot grasps a sensing probe or anemometer and measures the velocity of wind on every lattice point in the model. A software system was developed which permits us to check the avoidance of a model and a probe in advance.(2) A 1 : 2000 model of a ballpark was built. The detection of change in the velocity vector of wind and the temperature was tried when the treated sewage water is sprinkled. Effect of sprinkling is simulated by the on-off of the electrical power on film heaters placed at the diamond of field. Difference in magnitude of measurements could not be detected due to the poor resolution of sensing device used (0.lm/s and 0.1ﾟC) . It was found that the model should be simplified and scaled up.(3) To verify the effect of cooling of environment, water was sprinkled over pavement in front of a simple building , a six-storied and lOOm long , standing alone in a site of Kanazawa Institute of Technology . Descent of temperature 0.5ﾟC -lﾟC at altitude of 0.5m and wind velocity of 0.5m/s was observed . The computational model of this case was built and analyzed numerically. Descent of environmental temperature at altitude of 0.5m is evaluated as 2.3ﾟC.
