摘要
The drag coefficient bluegill sunfish Lepomis macrochirus was estimated from coasting deceleration as (mean +/- SD) 0.0154 +/- 0.0070 at a Reynolds number of 41,000 +/- 14,000. This was within the coasting range in other species and lower than values obtained from dead drag measurements in this species and others. Low momentum losses during coasting may allow its use during intermittent propulsion to modulate power output or maximize energy economy.
