The earliest mills - self-regulating or vaneless
windmills - were built of wood with a fan described as a "tulip" or a "box." Later mills were of the fixed wheel variety with a vane (or tail).
where [C.sub.x_N] is the axial component of the velocity at the nozzle exit, and [C.sub.x_VS] is the axial component of the velocity at the vaneless
The main components of the compressor are suction duct, impeller, vaneless
diffuser formed by the front and rear walls of casing and volute casing of circular cross section and delivery duct with a throttle outlet and nozzle at the inlet.

The impeller is followed by a vaneless
diffuser and a volute.
Produced by Milwaukee Lithograph Co., this poster is thought to predate 1890 based on the models featured (Halladay Standard, Halladay Vaneless
Turbocharger stand acoustic measurements from a centrifugal compressor with a vaneless
diffuser, splitter blades, and no casing treatment were presented by Figurella et al.
windmills used a counterbalance weight perched at the end of a wood beam to guide the wheel into the wind.
A year or so back, Lowell Devries from Historic Prairie Village museum near Madison, S.D., asked if I would build a set of fans for a Baker Monitor Vaneless
Model L windmill there.
