HUG Slab Wave

HUG Slab Wave

 

OCEAN WAVE ENERGY
OCEAN WAVE ENERGY

A slab is a piece of reef that sticks out in deep water or deep water sits behind it. Most slabs break in the same spot.  In the figure below, the HUG slab wave, 1, moves fast and hits a shallow reef, 4, at full speed. It lifts out of nowhere within seconds. HUG Slab waves are heavy reef breaks coming out of deep water and breaking in very shallow water. As a thick lip unloads on a shelf, the water doesn’t have anywhere to go but upwards overtopping into a reservoir with all their open-ocean energy intact. That energy gets focused as the depth suddenly decreases.

HUG Slab Wave

Acceleration = a = g (acceleration of gravity) = 9.8 m3/sec                                                                      (Final Velocity)2 = 2 x a x s

In the summer, the head of water is 1.5 m from water forcing through the automatic gates of the artificial reef:

Final Velocity = 5.42 m/sec for 1.5 m drop (s):

 In the winter, the head of water is 5 m from water washing over the walls of the artificial reef:

Final Velocity = 9.9 m/sec for 5 m drop (s) of the crest to sea level.

       Wave heights during storms may exceed 10 meters (33 feet)

 

HUG Slab Wave

  • Final Power of the Helical Turbine

The formula for Kinetic Energy is KE= ½ x A x V 3 x (.35) efficiency (A = area swept; Velocity)

Diameter of the Helical Turbine in the HUG is 1 m. The radius is 0.5 m: A = π r2 = π (0.5)2 = .785 m2      

  • = ½ x .785 m2 x (42 m/sec)3 x .35 = 21.9 kW/turbine in summer  x 7= .153 MW HUG System
  • = ½ x .785 m2 x (9 m/sec)3 x .35 = 132.6 kW/turbine in winter  x 7= .927 MW HUG System

The velocity of the speed at which a wave travels in winter: period is every 7 seconds for a velocity of 7.6 m/sec (25 ft/sec).

The average height is normally 3m to 4m (10 ft to 13 ft). The slab wave increases by 250%: 7.5 m to 10 m

The individual waves break when their wave height H is larger than 0.8 times the water depth h: a breaker 2 m high would occur in water 2.4 m deep.

 

HUG Slab Wave

Wave heights are amplified in the region of shallower water. At the wave period of 7 seconds, the significant wave height is 2 m high at depths of 12 m. The slab wave configuration raises the height to 5 m.

The formula for Kinetic Energy is KE= ½ x A x V 3 x (.35) efficiency (A = area swept; Velocity).       

 (Diameter of the Helical Turbine Area: 1 m) = .5 x .5 x 3.14 = .785 m2  The area of the throat of the HUG is .785 m2: radius is 0.5 meter.

HUG Slab Wave

Volume of Water from Slab Wave:

Required of the HUG System to empty Reservoir every 4 sec. period in summer & 7 sec. in winter:

Summer:

Helical Turbine Area: .785 m2 x Velocity of flow (5.42 m/sec) = 4.25 m3/sec. x 7= 30m3/sec 

Number of HUGs Required: 285/30 = 10 HUG Systems

IN: Volume of Slab Wave: 200 m long x 1.5m thick x 7.6 m/sec x 50% = 1,140 m3/4sec = 285 m3/sec

OUT: The HUG flow = .785 m2 x 5.42 m/sec = 4.25 m3/sec. x 7 HUGs x 10 HUG Systems = 298 m3/sec

Winter:

Helical Turbine Area: .785 m2 x Velocity of flow (9.9 m/sec) = 7.77 m3/sec. x 7 = 54.4 m3/sec 

Number of HUGs Required: 571/54.4 = 10 HUG Systems

IN: Volume of Slab Wave: 200 m long x 2 m thick x 10 m/sec = 4,000 m3/ 7sec = 571 m3/sec

OUT: The HUG flow = .785 m2 x 9.9 m/sec = 7.77 m3/sec. x 7 HUGs x 10 HUG Systems =545 m3/sec

The formula for Kinetic Energy is                                                                            KE= ½ x A x V 3 x (.35) efficiency (A = area swept; Velocity)

Diameter of the Helical Turbine in the HUG is 1 m. The radius is 0.5 m: A = π r2 = π (0.5)2 = .785 m2      

KE = ½ x .785 m2 x (5.42 m/sec)3 x .35 = 21.9 kW/turbine in summer  x 7= .153 MW x 10 HUG Systems  = 1.53 MW.

KE = ½ x .785 m2 x (9.9 m/sec)3 x .35 = 132.6 kW/turbine in winter x 7= .927 MW x 10 HUG Systems  = 9.27 MW.

Summer or Light or Wrong Wind Direction:                                                                                                          

During low tide, this wave energy is reduced by 15%: 1.53 MW reduced to 1.38 MW

In addition, waves can come from various angles and there is a possibility of losing up to 20% of the wave energy: 1.38 MW reduced to 1.1 MW in low tide. To counter this disadvantage, the height of the slab wave entering the Reservoir has been underestimated by 20% – 30%.

Tides or Poor Wind Direction:

During low tide, this wave energy is reduced by 15%: 9.27 MW reduced to 8.34 MW

In addition, waves can come from various angles and there is a possibility of losing up to 20% of the wave energy: 8.34 MW reduced to 6.67 MW in low tide. To counter this disadvantage, the height of the slab wave flooding into the Reservoir has been underestimated by 20% – 30%.

Size of the HUG Wave Energy

The important measurement is the front wall facing the wave, which are 100 m each and are at 90 degrees to each other.  As long as the water coming into the Reservoir is the same leaving, the entire size is based on how best to adapt to the present reef. The number of power barges is less than the Pump HUGs because the high pressure pipelines are combined.

 

HUG Slab Wave

If we increase the length of the front wall facing the wave, the power is double: 3 MW and 19 MW.

HUG Slab Wave

In a natural environment, many of these slabs are 20 feet from the rocks, which are too dangerous. You can build a safe slab wave environment with deep water and shallow shelves or create an abrupt depth change.  If it is safe slab surfing, surfers will come.
