Roll-to-roll web systems are widely used in modern industries, and register control is very important for product quality. This paper discusses the dynamic analysis and control of the register error in the speed-up phase. Based on the constant speed mathematical model, a mechanical model with undetermined coefficients is built and the coefficients are identified by the practical open-loop error curves...
Since the numerical simulation for two phase flow that couples the cavitation model with turbulent flow, remains as one of the challenging issues in the society and needs a long calculation time to achieve the result. Hence, based on the shared-memory multiprocessor, a parallel algorithm is designed to reduce the calculation time in this paper. The LES technology and Sauer cavitation model are used...
Parallel computation of the compressible turbulence with LES was performed with computational fluid dynamics. The Message Passing Interface (MPI) parallel environment was constructed based on Linux OS, and the corresponding parallel computational program with LES was developed by adopting the C Language. The approximate Reimann solver and two-step Runge-Kutta time-advance were adopted to solve the...
