The Effect of Clearance on Energy Dissipation for the Roots Power Machine Based on Low-Quality Energy Recovery

As a new type of waste heat conversion machine, the roots power machine can convert low-quality resources that are difficult to use into mechanical energy. In order study influence tip clearance and radial on experimental studies were conducted with having different combination clearances their performance was examined. A parametric undertaken using CFD find sensitivity these in influencing range 0.2-0.5 mm. From analysis, it inferred sensitive for 0.25-0.5 mm 0.2-0.25 Reduction from 0.5 0.2 caused an increase 10.368 11.423 % volumetric efficiency respectively.
