SBIR Phase I: Flexible Surface Deturbulator for Enhancing Automobile Fuel Efficiency

小企业创新研究（SBIR）第一期项目将开发一种柔性复合表面除湍流器（FCSD）胶带，以及将其粘贴在道路车辆上以减少空气阻力的方法。FCSD是一种薄的、无动力的设备，由一层柔性薄膜组成，拉伸在基板上的一系列条带上。然后，基材的背面可以粘合到道路车辆的表面上。在一个大的紊流尾流存在的情况下（如在潮湿的高速公路上行驶时出现的一大片喷雾），在公路车辆后面，去湍流器通过使空气在这个虚拟的船尾中停滞来减少阻力。尽管在风洞试验中观察到约80%的阻力减少，但为了优化长途卡车的除湍流器，将进行流-除湍流器相互作用的详细分析。减阻胶带实现的减阻效果将吸引美国和国外的潜在用户立即进行改造，以抵消不断上涨的燃料价格。它还将有助于减少卡车和汽车排放的有毒污染物和温室气体（二氧化碳）。

The Small Business Innovation Research (SBIR) Phase I project will develop a Flexible Composite Surface Deturbulator (FCSD) tape and methods for affixing it to road vehicles to reduce air resistance. The FCSD is a thin, non-powered device consisting of a flexible membrane stretched across an array of strips on a substrate. The back of the substrate can then be bonded to the surfaces of a road vehicle. In the presence of a large turbulent wake (as evidenced by a large plume of spray when driving on wet highways), behind a road vehicle, the Deturbulator reduces drag by making the air stagnant in this virtual boat-tail. Even though about 80% drag reduction has been observed in wind tunnel tests, a detailed analysis of the flow-deturbulator interaction will be performed in order to optimize the Deturbulator for long distance trucks. The drag reduction achieved with a Deturbulator Tape will attract potential users in the U.S. and abroad to immediately retrofit and counteract increasing fuel prices. It will also help reduce emissions of toxic pollutants and greenhouse gases (CO2) from trucks and automobiles.
