Flow resistance characteristics of self-repairing power law fluid flowing in two-size, net-shaped ducts
摘要
Abstract
In order to investigate the flow resistance characteristics of self-repairing non-Newtonian power-law fluid flowing in a two-size, net-shaped structure, analytical and numerical models were built. The relative flow resistance of a fluid moving from two-size duct structure to a uniform size duct structure was calculated. The analytical results show that when the volume of the fluid ducts is specified, an optimized two-size duct structure provides less flow resistance for most crack sites than a uniform size duct structure. The higher the power law index, the greater the advantage of the two-size duct structure. Typical numerical simulation results agree well with the analytical results, illustrating that when the svelteness number is high ( ＞ 10) and the Reynolds number of laminar flow is low ( ＜ 10), analytical solutions are accurate. The results provide new data and guidance for fluid duct optimization.关键词
