  • Tide - Wikipedia

    The semi-diurnal range (the difference in height between high and low waters over about half a day) varies in a two-week cycle. Approximately twice a month, around new moon and full moon when the Sun, Moon, and Earth form a line (a configuration known as a syzygy), the tidal force due to the Sun reinforces that due to the Moon. The tide's range is then at its maximum; this is called the spring ...

  • Multirotor Systems Using Three Shrouded Wind Turbines …

    To investigate the pressure distribution behind the MRS with three WLTs, we evaluated a nondimensional static pressure along the line A–A, which was just behind the turbines, as described in Fig. 16. Figure 17 shows the time-averaged pressure distribution. Here, the black line of MRS-3-180 shows the pressure distribution of a MRS with three WLTs.
