A Study of Filter Media Properties and Fiber Orientation

摘要：本文的目的是确定滤料纤维的取向和随机程度对滤饼形成过程中颗粒捕获效率和能量耗散的影响。将建立一个实验设施来测量微观（纤维取向、单个颗粒渗透和捕获、颗粒-纤维相互作用）和宏观（介质压降、流速、颗粒渗透量）过滤特性。将寻求对颗粒捕获和饼结构演化等机制的基本理解。保留效率和纤维取向之间的关系将被确定。主要应用于石油工业、地下水水文、化学加工、造纸和食品加工。＊＊＊

ABSTRACT CTS-9523524 The objective of this proposal is to determine the effect of the orientation and degree of randomness of the filter media fibers on particle capture efficiency and energy dissipation during cake formation. An experimental facility will be constructed to measure both the microscopic (fiber orientation, individual particle penetration and capture, particle-fiber interactions) and macroscopic (medium pressure drop, flow rate, amount of particle penetration) filtration characteristics. Basic understanding of mechanisms such as particle capture and evolution of cake structure will be sought. A correlation between the retention efficiency and fiber orientation will be determined. The main applications are in petroleum industry, ground water hydrology, chemical processing, paper making and food processing. ***
