拖网渔船船模试验数据

通过阻力试验，采用阻力仪测量船模不同浮态和航速下的阻力试验结果，结合经验公式，计算分析得到实船阻力，换算为实船功率曲线。为设计船舶达到设计航速选定主机功率。将船模速度(m/s)、实船速度(kn)、船模总阻力(N)、船模雷诺数、实船雷诺数、船模摩擦阻力系数、实船摩擦阻力系数、剩余阻力系数、船模总阻力系数、实船总阻力系数、入摩擦阻力1957-ITTC公式得出实船摩擦阻力、实船摩擦阻力、剩余阻力和实船总阻力。
最终通过实船总阻力Rts乘以实船航速乘以0.5144倍得到裸船有效功率；
通过裸船有效功率Peb乘以1加上附体和空气阻力相对于裸船体的比值（附体和空气阻力单体船为2~7%裸船体阻力，本船取6%），得到实船有效功率。

Resistance tests were conducted using a resistance dynamometer to measure the resistance of ship models under various floating states and speeds. Combined with empirical formulas, the full-scale ship resistance was calculated and analyzed, then converted into the full-scale ship power curve for selecting the main engine power required for the designed vessel to achieve the designed speed.

The measured and calculated parameters include: ship model speed (m/s), full-scale ship speed (kn), total resistance of ship model (N), ship model Reynolds number, full-scale ship Reynolds number, frictional resistance coefficient of ship model, frictional resistance coefficient of full-scale ship, residual resistance coefficient, total resistance coefficient of ship model, and total resistance coefficient of full-scale ship. The full-scale frictional resistance, residual resistance and full-scale total ship resistance are derived using the 1957 ITTC frictional resistance formula.

Finally, the bare hull effective power Peb is calculated by multiplying the full-scale total resistance R_ts by the ship's service speed and 0.5144. The ship's effective power is then obtained by multiplying Peb by (1 + the ratio of appendage and air resistance to the bare hull resistance). For monohull ships, this ratio typically ranges from 2% to 7% of the bare hull resistance, and a value of 6% is adopted for this vessel.
