| Research Abstract |
This study introduced a timed Petri net to realize system analysis of concurrent interactive processes in nonlinear waves of a shear flow with a diffusive exothermic reaction and nonlinear serum protein fractionation using liquid chromatography. Through modelling and simulation of the above processes, the following results were obtained.
1. Viscous nonlinear waves in a liquid shear flow with a diffusive exothermic neutralization were experimentally investigated and the mechanism of oscillation was modelled based on the quantization of reactants, heat and momentum using a timed Petri net. The dependence of viscosity on temperature was very important for the model.
2. In serum protein fractionation using liquid chromatography, the nonlinear effects of the overload and the concentration of injection were experimentally investigated and the nonlinear operation of fractionation could be represented using a timed Petri net.
3. Simulation based on the above models clearly showed the nonlinear relation between state variables and manipulated factors.
The above results made clear that the viscosity of liquid was the most important as a manipulated factor in the above processes.
