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源纳入我们的日常生活中。具体来说，本报告试图利用实验场模型来核实迄今为止所进行的实地实验的测量结果。(1)将5度运动关节机器人置于直线运动基座上，构建了测量系统。机器人抓住传感探头或风速计，测量模型中每个晶格点上的风速。开发了一个软件系统，可以提前检查模型和探针的回避情况。(2)建造了一个2000年的棒球场模型。试验了在处理后的污水洒洒时，对风速矢量和温度变化的检测。通过在场菱形处放置薄膜加热器的电源开关，模拟了喷淋的效果。由于使用的传感装置分辨率较差，无法检测到测量值的大小差异(0。lm/s和0.1‰C)。结果表明，该模型需要进行简化和按比例放大。(3)为了验证环境冷却的效果，在金泽工业大学场地内一座6层、6米长的简易建筑前的路面上洒水。在海拔0.5m、风速0.5m/s时，温度下降0.5ºC - 1ºC。建立了该案例的计算模型，并进行了数值分析。海拔0.5m的环境温度下降值为2.3ºC。

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.
