Euler method (ocean current observation) - Oirahou


[Methods for observing ocean currents]
Ocean current observation methods can be broadly divided into direct and indirect methods. Direct methods include the Euler method and the Lagrangian method. The Euler method measures the current by fixing a current meter in a certain place, and the strength of the current is measured using the propeller rotation speed and torque, the pressure on a plate or membrane, the inclination caused by the resistance when a wire is stretched, or the change in sound speed due to the Doppler effect. …

*Some of the terminology used in reference to the "Euler method (ocean current observation)" is listed below.

[海流の観測方法]
 海流の観測方法を大別すると直接法と間接法に分けられる。直接法にはオイラー法とラグランジュ法がある。オイラー法は流速計をある場所に固定して流れを測るもので,流れの強さは,プロペラの回転数やトルク,板や膜にかかる圧力,ワイヤを張った時の抵抗による傾き,あるいはドップラー効果による音速変化などを利用して測る。…
