Wind Energy

Wind energy is a renewable energy source that is used to generate electricity by wind power. The term, wind power, means utilization of kinetic energy of wind to generate electricity. Wind energy is termed renewable source energy because it can never be exhausted. There are other renewable energy sources, such as solar energy, geothermal energy, hydropower energy, and so on. All of them contribute to power the thermal energy stations to generate electricity.

Q1/The flow about a 150 mm artillery
projectile which travels at 600 m/s through
still air at 30°C and absolute pressure 101.4
kPa is to be modeled in a high-speed wind
tunnel with a 1:6 model. If the wind tunnel air
has a temperature of -18°C and absolute
pressure of 68.9 kPa, what velocity is
required? If the drag force on the model is
35 N, what is the drag force on the prototype
if skin friction may be neglected?
Q2/ A cavitation zone is expected on an
overflow structure when the flowrate is 140
m/s, atmospheric pressure 101.3 kPa, and
water temperature 5°C. The cavitation is to
be reproduced on a 1:20 model of the
structure operating in a vacuum tank with
water at 50°C. Disregarding frictional and
surface-tension effects, determine the
flowrate and absolute pressure (kPa) to be
used in the tank for dynamic similarity.
