This paper deals with the validation of the concept of using virtual commissioning of the low-level industrial control systems to adjust PID controller settings. General hardware configurations and logical layers of the experimental setups, which were used during the experiments, are shown and described in details. It is shown how to determine the controller settings using pre-tuning and fine-tuning functionality, available in standard Siemens® Function Blocks Library, that have been launched in virtual commissioning environment. Comparison of the results is a basis to answer the question if the modern virtual commissioning tools currently used in industry have sufficient accuracy to be used as a master tool for the initial PID controller tuning. It is also important to know whether these systems are suitable for use as Industry 4.0 tools, as the simulation is one of its most important part. The first section in your paper

“…The distributed nature of HXs and their loops brings about a necessity for advanced ad-hoc modelling strategies. To name just a few, a combination of distributed-parameter HX modelling and a spatial orthogonal-collocation discretization [ 8 ], a one-dimensional discretization of heat transfer balance equations [ 9 ], the conservation of mass and energy principle improved by log-mean-temperature-difference approach [ 10 ], or simplifying the convective-diffusion equations of the fluid flow [ 11 ].…”

Experimental research has been carried out for four individual heat exchanger constructions, i.e., plain double tube, turbulized double tube, plain U-bend and U-bend with turbulator. Tests were made for the water-water system. The study covered a wide measuring range, i.e., Re = 800-9000 -on the shell side, for a constant cold water temperature of 9 • C and hot water of 50 • C. The heat exchangers were made from copper tubes with external diameter of 10 mm and 18 mm respectively and wall thickness of 1 mm. The helicoidal vortex generator was made from brass wire with a diameter of 2.4 mm, coil diameter of 13 mm and pitch of 11 mm. For these geometries, the values of pressure drop, heat flux and heat transfer coefficient were determined. Wire coil turbulator increased the heat transfer coefficient (HTC) over 100% and pressure drop up by 100%. The comparison of heat transfer efficiency was performed based on the number of transfer units-effectivenes (NTU-ε) method. The modified construction achieved a similar efficiency. Economic analysis of wire coil turbulator was made to validate its use in the system. It showed that a coiled wire turbulator can greatly decrease the investment cost of the double tube heat exchanger while maintaining transferred heat at a constant level.
