Investigate the 'turbine blade
(for jet engine) making process'
Hint: Turbine blade is made of superalloy. Recently, it shows the
single crystalline structure.
Format: Format is the same with previous homework. A4 up to 4-5
page. Photo and figures are welcome. References should be
written.
Topic: Agitation
A flat-blade turbine agitator with disk having six blade is
installed in a tank. The tank diameter (Dt) is 1.83 m,
the turbine diameter (Di) is 0.61 m and the width (w) is
0.122 mm. The tank contains four baffles, each having width (J) of
0.15 mm. The turbine operate (N) at 90 rpm and the liquid in tank
has a viscosity (u) of 10 cP and a density (p) of 929
kg/m3. It is desired to design...
The rotor of a kaplan turbine is 2.8m in dia. at the
blade tips and 0.9m at the hub. Its speed of rotation is 110r/min.
Water enters the rotor without shock, making an angle of 37° to the
axial direction at the mean dia and rotor has a blade exit angle of
58° to the axial direction at the mean diameter. The available
pressure head is 6.5m .Determine 1) the inlet angle of the rotor
blades at the mean dia....
An airfoil profile to be used on a wind turbine blade is tested
in a wind tunnel. The prototype (full-scale) airfoil section has a
chord length of 2m and moves at 50 m/s relative to the wind, the
wind tunnel model has a chord length of 0.4m. The temperature for
the model test is the same as for prototype operation.
(a) What criterion should be used to obtain dynamic similarity
in the experiment? (Write out the criterion in an equation.)...
consider the turbine blade tip available in the
laboratory of University and discuss the needs of cooling
technology specially specially to be used for the blood tree using
photo and 77 develop a mathematical model and show the effect of
wearing the dimensions of the blood type on its performance discuss
also the effect of film cooling and unsteady turbulence something
pulling film hall and gauge arrangement to be made and enhancement
in the cooling techniques which we can implement...
A 3-blade wind turbine with a diameter of 16 m spins at 35 rpm
at a 5000 m elevation where the average wind speed is 30 km/hr. The
atmospheric pressure and temperature at that location are 98 kPa
and -10 oC, respectively. There is a rotating wake behind the
turbine. Neglecting the frictional drag, calculate the maximum
power coefficient and maximum power.
A turbine blade of solution annealed INCOLOY alloy 800 is 18 in
long and operates at 1400 degrees Fahrenheit. If the tip clearance
is 0.2 in and centrifugal forces induce an average longitudinal
stress of 10 ksi. After how many hours is expected the blade to
interfere with the turbine stator due to creep?
