Verma, S K (2014) Numerical investigation on the performance of roots blower varying rotor profile. MTech thesis.
Root/Lobe is the most essential part of Roots blower and its design affects the operating performance directly. So, the rotor profile must be improved so that the flow area is maximized while the leakage is minimized and friction due to meshing between the rotor surfaces is made as small as possible. Here an attempt has been made to study the performance of a root blower numerically by varying the shape of the rotor profile. Finite Volume Method (FVM) has been adopted here to perform the hydrodynamic calculations. Four different profiles have been considered by varying the west width of the rotor. Pressure contour, Temperature contour, velocity contour, velocity vector mass flow rate etc. have extracted for each of these rotor profile and have been compared.
