研究了雷诺数、网眼密实度和网格形状以及水流方向对浸没式网箱拖曳阻力的影响。提出了新的法向阻力系数和切向阻力系数的计算公式。公式中的未知常数是根据平面网拖曳水池中的实验数据确定的。经实验验证，该公式同样适用于圆柱网。推导了正方形和正方形菱形网格网在平面和圆柱网状网上的总法向阻力的解析公式。(C)2005 Elsevier B.V.保留所有权利。
The effects of Reynolds number, net solidity and mesh pattern, and flow direction on the drag force on submerged nets of fish cages are studied. New formulae for the normal and tangential drag coefficients are proposed. The unknown constants in the formulae are determined from experimental data obtained in a towing tank for planar nets. It has been verified experimentally that the formulae are also applicable to cylindrical nets. Analytical formulae are derived for the total normal drag on planar and cylindrical nets with either square or square diamond mesh patterns. (c) 2005 Elsevier B.V. All rights reserved.
