In many industrial gas turbine compressor designs, the compressors later stage blade angles are reduced in a constant flow area section as a means to even out the per stage workload. Most compressors use NACA 65 series type airfoils, which are good f

The so-called “sudden death reaction” theory, for a diffusion flame, assumes that the fuel and oxidizer diffuse toward a stoichiometric concentration surface, and then suddenly disappear, due to their combustion which produces water and carbon di

The Universal Electric Machine (UEM) separates the speed of the magnetic field on the rotor from the mechanical speed of the rotor. This fundamental ability has numerous consequences that are very appealing in the power industry. The UEM is capable o
