VISCOUS SHEAR COMPRESSOR
A grooved plate viscous shear compressor under polytropic flow conditions is analyzed. Dimensionless curves for calculation of pressure ntse as a function of flow are given for isothermal compression, adiabatic compression (monatomic gas), and adiabatic compression (diatomic gas). Sample results are given in graphical form for a specific size compressor operating at 24,000 rpm with four different film thicknesses, ambient pressure, and temperature under isothermal and adiabatic conditions with air and helium, The viscous shear compressor is characterized by its high pressure rise, low flow, and low efficiency. The compressor can generate higher pressures at equal tip speeds than other types. The pressure rise and efficiency are highly dependent on minimum film thickness. As the level of ambient pressure increases so does the efficiency, at the same time peak efficiency shifts to the left on the pressure rise flow characteristic curve. (N,W.R.)
