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

小型企业创新研究(SBIR)第一阶段项目将开发一种柔性复合表面减震器(FCSD)胶带和将其粘贴到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，横跨基板上的一系列条带。然后，基板的背面可以粘合到道路车辆的表面上。在公路车辆后面的大型湍流尾流中(如在潮湿的高速公路上驾驶时的大量喷雾所证明的)，消扰器通过使空气在这个虚拟的船尾中停滞来减少阻力。尽管在风洞试验中已经观察到了大约80%的减阻效果，但为了优化长途卡车用的减振器，仍需对流动-去扰器的相互作用进行详细的分析。通过减震器胶带实现的减阻将吸引美国和国外的潜在用户立即进行改造，并抵消不断上涨的燃料价格。它还将有助于减少卡车和汽车的有毒污染物和温室气体(CO2)的排放。

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.
