In this paper, the process of gas flow in path a turbomolecular vacuum pump using Cercignani-Lampis (CL) model was simulated. CL used as new boundary conditions when calculating transition probability. The test particle method (Monte Carlo method) simulation. calculation molecules probability through blade channel forward and reverse directions, resulting probability, compression ratio made.

All efforts in advanced management systems should maximize value for the customer. One effective way to identify and realize this is map product's flow from end customer a supplier by visualizing streams of individual processes. This paper aims analyse propose introduction lean stream vacuum pump assembly achieve increased production output. Vacuum technology field engineering concerned with cr...
