Dispersion coefficients for turbulent flow are commonly available, but the common models are not easily implemented for fast computation of dispersion in timedependent large flow systems.Criteria were developed to aid in the choice of parameters for a model combining plug flow with the N-continuously-stirred-tanks model to obtain the best agreement with the pure axial-dispersed plug-flow model, while simultaneously being computationally efficient. Solution accuracy and computational savings were demonstrated for a realistic food industry example. The proposed model includes a method of structuring the discretization to handle the simulation of pressure drop and momentum balance simultaneously with simulation of dispersion.The criteria were derived from the analysis of Laplace transforms. It was also shown that the proposed model predicts the response to a step change in concentration in agreement with the exact solution of the axial-dispersed plug-flow model.The model was written in the object-oriented language Modelica as an object in a library structure which is being developed to simulate complex liquid food process lines and their control systems.

“…The better the model parameters, such as enzyme and cell kinetics, are tuned, the more comparable the operating values become. Furthermore, high model accuracy and robustness [35,36,[39][40][41] are required in order to allow effective training at critical conditions such as starting a centrifuge, emptying tanks or controller malfunctions.…”

Abstract:Operator training simulators (OTS) are software tools for training process operators in large-scale industrial applications. Here, we describe the development, implementation and training of an OTS for a large-scale industrial plant for bioethanol production. The design of the OTS is based on conceptual analysis (previously reported by us in this journal) of various configuration alternatives and training procedures at the plant. In this article, we report on how the conceptual design is used in simulation models and graphical user interfaces and how the design is applied for training of operators in the real plant environment. The results imply that OTS would be time-and cost-efficient tools for application in the biotechnological industry.

“…This is especially the case in the discrete manufacturing sector, which includes the manufacturing of automotives, mechanical & electrical equipments and appliance etc [1]. However, in the process manufacturing sector, such as oil and chemical processing, ore dressing, and non-ferrous metallurgical processing, the practice of 3D visual simulation is less common [2]. There are probably two reasons.…”

3D virtual simulation has been widely used in the design of manufacturing plants. This paper focuses on the application of 3D virtual simulation in process industry. It discusses the impacts of the characteristics of the process manufacturing and the simulation users requirements on the integration of 3D visual simulation and process simulation. An actual case of grinding circuit simulation is introduced. The hardware in the loop simulation structure and the real-time data integration techniques are discussed in detail. Finally, a solution of real-time integration is provided.Index Terms-grinding process; 3D visual simulation; hardware in the loop simulation
