BIDIRECTIONAL FLOATING HYDRO TURBINE

PRESENTED BY

ADITYA A. PANCHAL

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.”

PRINCIPLE

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

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.

OBJECTIVES

Our main objective is to generate electricity from conventional resources [water] using bidirectional floating hydro turbine.

To study the principle of hydro turbine using suspension system

DESIGN OF TURBINE BLADE

Material- GFRP(Glass fiber Reinforce polymer)Thickness of blade material = 5mmCross section area of blade = 5 x 650 = 3250 mm

TURBINE BLADE CALCULATIONGFRP Glass fiber

reinforced polymer (60 vol% E-glass)

Density 2000 [kg.m-3]

Strength160 [N.mm-2]

 We knowDrag 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

Fd = 0.5 x 1000 x 0.65 x 0.11 x 62

Fd = 1287 kg = 12870 N

Thickness of blade material = 5mmCross section area of blade = 5 x 650 = 3250 mmInduce 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 RR = (280 / 2) + (110/2 ) = 195 mmT = 12870 x 195 =2509 N m

Design of Turbine

OUTER DIAMETER:500 mmINNER DIAMTER:280 mmLENGTH:650 mm

Materials :- GFRP Glass fiber reinforced polymer (60 vol% E-glass) Density (ρ):- 2 gm/cm3

Volume of turbine (v1)= (D02 - Di

2) l = (5002 - 2802) 650 = 87.60106 mm2

Volume of a blade = l h b = 6501105 = 357103 mm3

No. of blades = 6Therefore, total no. of blades(v2) = 357103

= 1.785106 mm3

Therefore, total volume of turbine (v)= v1 + v2

= 5.9106 + 1.785106

= 7.685106 mm3

Design of Shaft

Diameter of shaft:103mmMaterail-C-40

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) = Fs induced ds3 

128700 = fs induced 203

Fs induced = 81.9 N/mm2

As induced stress is less than allowable design is safe

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.
