As for a turbine wheel
, similar design method as for the impeller was adopted.
x = [c.sub.2]/[r.sub.2] [[omega].sub.0] is dimensionless speed; [[omega].sub.0] is engine angular speed; [T.sub.1] = [M.sub.P]/[rho][A.sub.2][r.sup.3.sub.2][[omega].sup.2.sub.0] is dimensionless moment of the pump wheel; [T.sub.2] = [M.sub.T]/[rho][A.sub.2][r.sup.3.sub.2][[omega].sup.2.sub.0] is dimensionless moment on the turbine wheel
, [Q.sub.1] = [J.sub.1]/[rho][A.sub.2][r.sup.3.sub.2] is dimensionless moment of inertia of the pump side; [Q.sub.2] = [j.sub.2]/[rho][A.sub.2][r.sup.3.sub.2] is dimensionless moment of inertia of the turbine side; p = [PHI]/[r.sub.2] is dimensionless parameter length.
To operate the probe, compressed air is introduced into the touch probe via the taper shank, and powers a turbine wheel
inside the touch probe.
This actually happened to the pilot of a factory-new Cirrus SR22 Turbo near Reno, Nev., in July 2007, the result of what appears to be one of the rarer turbo failure modes: A catastrophic failure of the turbocharger's hot-side turbine wheel
This hydroelectric system generates a whopping 7,200 kWh per month at a continuous output of 10,000 watts using an 8-inch Pelton turbine wheel
, directly driving a brushless 12-kilowatt alternator.
The turbine wheel
rotates at a speed proportional to the flow rate.
The device utilizes a miniature turbine wheel
and infrared beams to precisely achieve 10:1 or better turndown ratios with repeatability of [+ or -] 0.25% full scale and accuracy of [+ or -] 2% full scale.
With the wastegate turbo, a small turbine housing is used to increase the pressure to the turbine wheel
at low exhaust gas flows.
A fuel flow transducer is an electromechanical device, since it converts the energy of the spinning turbine wheel
to electronic signal pulses, which are passed along to a microprocessor and then displayed on a control head or on a GPS navigator (generally on a fuel endurance utility page).
This arrangement keeps the exhaust pulses separated from the next cylinder in the firing order so that there aren't any mixing losses and there is maximized pulse energy to the turbine wheel
, which means quicker torque delivery, similar to a twin-turbocharger setup.
The exhaust gas pulses from each bank of three cylinders are fed through two separate channels to the turbine wheel
. This produces maximum power of 320 hp, at 5,800 to 6,000 rpm, from a displacement of 3.0 litres allowing the BMW 640i Gran CoupEa to accelerate from 0 to 100 km/h in 5.4 seconds.
