It mainly explains about generation of electricity using floating hydro turbine using spring suspension system .The main important factor is the turbine generates electricity when the wave enter and leave the coast.In this the design is also explained about each and every part in the following PPT

PRESENTED BY
ADITYA A. PANCHAL

2. CONCEPT
“The FHT could be used to produce both wave
energy and energy from tidal current at the
same time. The turbine converts water power
into rotational power at its shaft, which is then
converted to electrical power by the dynamo.”

3. PRINCIPLE
It works on the principle of conversion of
kinetic energy of water (wave) into electrical
energy using dynamo and floating turbine.

4. PROBLEM DEFINITION
 TO UTILISE TIDAL FLOW OF WATER BY
CONVERTING ITS K.E. INTO WORK USING
BIDIRECTIONAL FLOW TURBINE.
 TO OVERCOME THE DEFECTS AND SAVE
COST IN POWER GENERATION FROM
OTHER CONVENTIONAL SOURCES OF
HYROPOWER.

5. OBJECTIVES
 Our main objective is to generate electricity from conventional

SHAFT C-40
TURBINE BLADE FIBER REINFORED POLYMER
DYNAMO 12 WATTS

10. DESIGN OF TURBINE BLADE
Material- GFRP(Glass fiber Reinforce polymer)
Thickness of blade material = 5mm
Cross section area of blade = 5 x 650 = 3250 mm

11. TURBINE BLADE CALCULATION
GFRP Glass fiber
reinforced polymer
(60 vol% E-glass)
Density
2000 [kg.m-3]
Strength
160 [N.mm-2]
We know
Drag force Fd = 0.5 x ρ x A x V2
Where,
Air Density (ρ):- 1000 kg/m3
Area of turbine blade A in m2
Air velocity V in m/s

12. Fd = 0.5 x 1000 x 0.65 x 0.11 x 62
Fd = 1287 kg = 12870 N
Thickness of blade material = 5mm
Cross section area of blade = 5 x 650 = 3250 mm
Induce stress Fc = F / A = 12870/ 3250 = 3.96 N / mm2
Allowable compressive stress for GFRP is 160 N / mm2
So selection of thickness of turbine blade
is safe under given condition.
So torque on turbine blade = F x R
R = (280 / 2) + (110/2 ) = 195 mm
T = 12870 x 195 =2509 N m

13. Design of Turbine
OUTER DIAMETER:500 mm
INNER DIAMTER:280 mm
LENGTH:650 mm

14. Materials :- GFRP Glass fiber reinforced polymer (60 vol% E-glass)
Density (ρ):- 2 gm/cm3
 Volume of turbine (v1)=

×(D0
2 - Di
2) × l
=
𝜋
4
×(5002 - 2802) × 650
= 87.60×106 mm2
 Volume of a blade = l × h × b
= 650×110×5
= 357×103 mm3
No. of blades = 6
Therefore, total no. of blades(v2) = 357×103× 5
= 1.785×106 mm3
Therefore, total volume of turbine (v)= v1 + v2
= 5.9×106 + 1.785×106
= 7.685×106 mm3

15. Design of Shaft
Diameter of shaft:103mm
Materail-C-40

16. Design of Shaft
 Material: C-40
Tangential force (Ft) = 340N/mm2
Shear force(Fs)allowable = 170N/mm2
CALCULATION OF DIAMETER OF SHAFT
We know torque applied by turbine blade T = 128700 N m
 Torque (T) =
𝜋
16
× Fs induced ×ds3
128700 =
𝜋
16
× fs induced× 203
Fs induced = 81.9 N/mm2
 As induced stress is less than allowable design is safe

17. Power Calculation
 Calculation of Power O/P in Watts:
Power, P =0.5 × 𝜌 × 𝐴 × 𝑉3 × 𝐶. 𝑃
Where,
𝜌 = Density of air
A = Area of Exposed Surface.
V = Velocity of air.
C.P = Co-efficient of Power =0.15
Calculation of Discharge:
∴ 𝑃𝑜𝑤𝑒𝑟, 𝑃 = 𝑂. 5 × 𝜌 × 𝐴 × 𝑉3
× 𝐶. 𝑃
= 0.5 × 1.2 × 0.65 × 0.5 × 203 × 0.15
P = 234 watts

24. RESULT AND CONCLUSION
 As per our setup we were able to glow a 3v and
12v LED lamp for the average speed of 135 rpm.
 Hence we are able to generate energy from tidal
waves which in turn can be stored in battery for
future use.
 By Above Study we concluded that this is Good
alternative Source for current methods for
Generation of Electricity.
