Integration of aero-elastic belt into the built environment for low-energy wind harnessing: current status and a case study

摘要: Low-powered devices are ubiquitous in this modern age especially their application the urban and built environment. The myriad of low-energy applications extend from wireless sensors, data loggers, transmitters other small-scale electronics. These which operate microWatt to milliWatt power range will play a significant role future smart cities providing for extended operation with little or no battery dependence. Low energy harvesters such as aero-elastic belt suitable integration sensors electronic therefore there is need studying its optimal installation conditions. In work, case study presenting Computational Fluid Dynamics modelling building integrated belts (electromagnetic transduction type) was presented. simulation used gable-roof type model 27° pitch obtained literature. atmospheric boundary layer flow employed incident wind. work investigates effect various wind speeds locations on performance device giving insight potential harvester into environment. The apex roof yielded highest output due speed-up maximisation region. This location produced largest under 45° angle approach, generating an estimated 62.4 mW accelerated position up 6.2 m/s. For velocity 10 m/s, approximately 14.4 m/s 37.5% at particular height. occurred oncoming 30° relative facade. equal 4.7 0° direction, airflows facade edges were fastest 5.4 indicating 15% along building.
