  • Optimized Blade Design for Homemade Windmills

    The wind pressure is the amount of force exerted by the wind per unit area of the blades and is given by: P = 1/2 (1 + c) * ρ * v 2 Where c is a constant and equals 1.0 for long flat plates. The force of the wind against the windmill blade is based on the wind pressure multiplied by the area of the blade facing the oncoming flow.

    Today, things have come full circle, if you will and there is now a growing demand for large, technologically advanced windmills across the world. The term wind energy or wind power describe the process through which wind turbines convert the kinetic energy in the wind into electrical energy by the use of generator.

  • Question Answers on Steam Turbines

    Answer: Reaction turbines have axial thrust because pressure on the entering side is greater than pressure on the leaving side of each stage. To counteract this force, steam is admitted to a dummy (balance) piston chamber at the low-pressure end of the rotor. Some designers also use a balance piston on impulse turbines that have a high thrust.

    Colloid mill works on the rotor-stator principle. The equipment breaks down materials by forming dispersion of materials in a liquid.

To reduce wear, the rotor and stator are constructed using toughened steel or corundum.

  • Physics of Wind Turbines

    Because the mass flow must be continuous, the area A 2 after the wind turbine is bigger than the area A 1 before. The effective power is the difference between the two wind powers: If the difference of both speeds is zero, we have no net efficiency. If the difference is too big, the air flow through the rotor is hindered too much.
