Cable concrete mats consist of a series of individual, precast concrete blocks, linked together by stainless steel cables andconfigured in the shape of rectangular mats, with spaces between blocks to allow vegetation to grow through and over them, andare used by contractors and engineers to control soil movement in culverts, spillways and storm drains, and in the construction ofroads and access ramps. International Erosion Control Systems (IECS) has established the erosion control and energy dissipationcharacteristics of its current products through extensive experiments conducted on prototype CCMs and developed a databaseand model algorithm for product selection based on design requirements for a particular application. New product expectationsand site-specific customization are often outside the limits of the current model and thus, limits its utility in many modernapplications. This project will develop a novel approach for product characterization utilizing computational fluid dynamics (CFD).CFD will provide an approach to enhance the fidelity of their current database, develop an accurate database for new products,and provide a means for conducting analysis of customized products in a timely and cost-effective manner. This approach willenable IECS to improve existing products to enhance their competitiveness in the existing market, and enable them to developunique new and custom products in an efficient and cost-effective manner so that they can compete in emerging markets inCanada and abroad.

电缆混凝土垫由一系列单独的预制混凝土块组成，通过不锈钢电缆连接在一起，并以矩形垫的形状配置，块之间的空间允许植被通过它们生长，承包商和工程师使用电缆混凝土垫来控制涵洞，溢洪道和雨水沟中的土壤运动，以及道路和入口坡道的建设。国际腐蚀控制系统公司（IECS）通过对原型CCM进行广泛的实验，确定了其当前产品的腐蚀控制和能量耗散特性，并根据特定应用的设计要求开发了一个数据库和模型算法，用于产品选择。新产品的期望和特定于站点的定制通常超出了当前模型的限制，因此限制了其在许多现代应用中的实用性。该项目将开发一种利用计算流体动力学（CFD）进行产品表征的新方法。CFD将提供一种方法，以提高其当前数据库的保真度，为新产品开发准确的数据库，并提供一种及时和经济有效的方式对定制产品进行分析的方法。这种方法将使IECS能够改进现有产品，以提高其在现有市场上的竞争力，并使他们能够以高效和具有成本效益的方式开发独特的新产品和定制产品，以便他们能够在加拿大和国外的新兴市场中竞争。
